The great thing about you is that you're still here. You made it through many stormy seas and you're still ready to get back in the boat. You're still brave enough to hope. You're still courageous enough to love. You still give of yourself with the same warmth you did before others tried to extinguish your flame. You're still filled with kindness even though the world hasn't given you much to be kind about. You're still open to great adventures and deep emotions. You're still here. You're still living. You're still you. How great it is that you're still you. — Emily Maroutian

Never underestimate the power of kindness. It is very contagious. A person whose heart is saddened by the troubles of this world, the loss of a friend or family member, a hard days work, or the struggle of provision can experience joy through a simple act of kindness. Romans 12: 10-12, Be kindly affectionate to one another with brotherly love, in honor giving preference to one another, not lagging in diligence, fervent in spirit, serving the Lord, rejoicing in hope, patient in tribulation, continually steadfastly in prayer. — Amaka Imani Nkosazana

Pema calls these activities "the six ways of compassionate living": generosity, patience, discipline, exertion, meditation, and prajna, or wisdom. The basis for all these practices is the cultivation of maitri, an unconditional loving-kindness with ourselves that says, "Start where you are." In Buddhist terms, this path is known as bodhisattva activity. Simply put, a bodhisattva is one who aspires to act from an awakened heart. In terms of the Shambhala teachings, it is the path of warriorship. To join these two streams, Pema likes to use the term warrior-bodhisattva, which implies a fresh and forward-moving energy that is willing to enter into suffering for others' benefit. Such action relates to overcoming the self-deception, self-protection, and other habitual reactions that we use to keep ourselves secure - in a prison of concepts. By gently and precisely cutting through these barriers of ego, we develop a direct experience of bodhichitta. — Pema Chodron

From some Christians as far back as the twelfth century, certainly from farther back in so-called primitive cultures, and from some ecologists of our own time, we have the idea of a great kindness including and binding together all beings: the living and the nonliving, the plants and animals, the water, the air, the stones. All, ultimately, are of a kind, belonging together, interdependently, in this world. From the point of view of Genesis I or of the 104th Psalm, we would say that all are of one kind, one kinship, one nature, because all are creatures. — Wendell Berry

Boundless compassion for all living beings is the surest and most certain guarantee of pure moral conduct, and needs no casuistry. Whoever is filled with it will assuredly injure no one, do harm to no one, encroach on no man's rights; he will rather have regard for every one, forgive every one, help every one as far as he can, and all his actions will bear the stamp of justice and loving-kindness. — Arthur Schopenhauer

That was what counted, she told herself: those unexpected moments of appreciation, unanticipated glimpses of beauty or kindness - any of the things that attached us to this world, that made us forget, even for a moment, its pain and its transience. — Alexander McCall Smith

Humanism is the purest expression of your soul as a human. It has no God to be concerned with, except for the living Gods, that is the humans. It has no doctrine to abide by, except for the natural doctrine of love and benevolence. That's the religion we need my friend. — Abhijit Naskar

If everybody did just one thing. Just one thing. Not even a great thing. Not a world-changing thing, just one blessing, just one act of living kindness.

Oldster

We who make stories know that we tell lies for a living. But they are good lies that say true things, and we owe it to our readers to build them as best we can. Because somewhere out there is someone who needs that story. Someone who will grow up with a different landscape, who without that story will be a different person. And who with that story may have hope, or wisdom, or kindness, or comfort. And that is why we write. — Neil Gaiman

People who live in cold climes must keep warm by kindness," Orvo spoke softly in reply. "I think that is how every person should be. Kindness -- it's the same as having a head, a nose, a pair of feet . . . There are many nations living on the earth. Each of their people carries a seed of suspicion toward those not of their own tribe. Oftentimes, they won't even see the people of another tribe as real human beings. . . . — Yuri Rytkheu

The brief story of the supper at Emmaus carries within it a number of core principles of the Christian life as Luke understands it. First, the idea that one comes to know Christ through acts of generosity to other human beings. It is because of their kindness to a stranger that the disciples find the beloved teacher whom they had lost. Second, there is the idea that they can conjure his presence in prayer and in communal acts such as the breaking of bread - by remembering his life, death, and resurrection - even in an undistinguished house in an anonymous village. The simple acts of generosity and community in daily life are the acts that make real the living presence of Jesus. — Kate Cooper

Never allow anyone to take advantage of you in no shape form or fashion. People get into relationships for different reasons. And, many are often looking for something in return and it mostly relates to security.

Each person in a relationship should be able to contribute wholly and completely. — Amaka Imani Nkosazana

When the days are too short, chances are you are living at your best. — Earl Nightingale

Be the living expression of God's kindness; kindness in your eyes, kindness in your face, kindness in your smile, kindness in your warm greetings. We are all but His instruments who do our little bit and pass by. I believe that the way in which an act of kindness is done is as important as the action itself. — Mother Teresa

You make the choice concerning who you associate with on a daily basis. Whenever there are people around you who continually gossip or nag, you have the option to entertain that nonsense or leave it alone. The choice is yours. Most of the time people you hang around are a reflection of yourself. We often times attract people with like-minded personalities. So, if you enjoy that type of company it says much about your character. — Amaka Imani Nkosazana

What multiplies is only up to us. Whether it is kindness that multiplies; or unkindness. Whether it is goodwill that multiplies; or bad intentions. Whether it is love that multiplies; or fear. Whether it is truth that multiplies; or doubt. What multiplies in our own minds, in our relationships with other people, in our relationship with our perspectives about the rest of the world, in our relationship with God, in our outlooks and in our hearts - it's all up to us. The power of multiplication is in our own hands. What you magnify upon will in fact become your reality. — C. JoyBell C.

In God's scheme what is a few billion years here and there. Perhaps there have come and gone a dozen human civilizations in the past billion years that we know nothing about.

Then, finally, one of these civilizations, say five billion years from now, will last because people treat each other the way they ought to. — Leon Uris

If we simply imagined that everyone who crossed our path was living out his or her very last day on Earth, we might treat people as kindly as we ought to each day they lived. — Richelle E. Goodrich

One of the most spiritual things you can do is embrace your humanity. Connect with those around you today. Say, "I love you", "I'm sorry", "I appreciate you", "I'm proud of you" ... whatever you're feeling. Send random texts, write a cute note, embrace your truth and share it ... cause a smile today for someone else ... and give plenty of hugs. — Steve Maraboli

He thought of death in its infinite groanings, of Aztecs ripping out living hearts and of cancer and three-year-olds buried alive and he wondered whether God was alien and cruel, but then remembered Beethoven and the dappling of things and "Hurrah for Karamazov" and kindness. He — William Peter Blatty

For we ourselves were also once foolish, disobedient, deceived, serving various lusts and pleasures, living in malice and envy, hateful and hating one another. But when the kindness and the love of God our Savior toward man appeared, not by works of righteousness which we have done, but according to His mercy He saved us, through the washing of regeneration and renewing of the Holy Spirit, whom He poured out on us abundantly through Jesus Christ our Savior, that having been justified by His grace we should become heirs according to the hope of eternal life. TITUS 3:3-7 — Stormie O'martian

The whistling dawn, the sussurration of the leaves, a honking goose, and then a sentimental confab at the Solid Rock Gospel Church with a wounded soul who poured his heart out to Press precisely because he was blind and therefore harmless. Since these individuals had no money, he couldn't give them financial advice, just wholehearted sympathy. As at the commune, a toddler might scramble into his lap, and while he petted the child its mother held a cookie to its mouth and another one to his to bite and chew.
A world worth living in and for. — Edward Hoagland

...the act of kindness is an unselfish act, it is medicine for your soul... — Travis Culliton

Our world desperately needs change. We all know this. The scope of the change ranges from our lifestyles to the direction of our civilization.

If you have a big idea or plan that you desire to execute, don't depend solely on others to appreciate your efforts. You must have the ability to encourage yourself.

Never build your hopes and dreams based primarily on the accolades from others. You may discover a rude awakening. — Amaka Imani Nkosazana

What if today you gave yourself permission to be outrageously kind? What if you extended as much good will and kindness as you can possibly muster to every person you meet? And what if you did it with no thought of reward? I'm sure of one thing: it will be a day you will never regret. — Steve Goodier

How is one statute against murder or rape or theft different from any other?" I said, though my mind had careened into a hundred different questions. "They are different in that they come from a god who says we are to show honor of him by honoring others. And so as we feed our hungry neighbor and do not steal from him we honor not our neighbor, but the image of the One who fashioned him. You say our god has no face. This is not true. Yaweh's face is before us in every person we see, as we are made in his image. Living people who require more kindness and adoration than any idol. — Tosca Lee

Kindness and compassion toward all living things is the mark of a civilized society. — Cesar Chavez

Practice kindness all day to everybody and you will realize you're already in heaven now. — Jack Kerouac

How will people remember you when you are gone? And for how long until they forget? Were you selfish or selfless? A gossip or a patient listener? Did you add value to the world, or did you simply take from it? Did you add value to the lives of others, or did you take the value out of someone's life? Were you a plus or negative? Meaningful or meaningless? Do you live to take or live to give? — Suzy Kassem

Standardisation of intellectual and emotional patterns had become extreme. A main mechanism for achieving this was a device that supplied identical indoctrinational material simultaneously into every living or working unit, whether that of a single person, a family, or an institution, through a whole country. These programmes were standardised, particularly for children. At best they reinforced a low level of ethic - kindness to animals, for instance - but the worst was inherent in the sheer fact of the infinite repetition. — Doris Lessing

I look around me and see all the problems.
I know people aren't living the gospel.
I know they are too busy.
The world is too loud.
The sounds you hear in the hall or not
the substance of love and kindness.
I hear gossip, I hear spite, I hear fear.
I do not hear the gospel.
Except inside me, I can feel it there. — David Levithan

live with somebody, peaceably, dreaming beside each other, sharing meals, making a family, but there seems no special excitement to it, even though you know, as Tim did, that you're living with a person of exceptional kindness. And then she's gone and the depth of the loss almost surpasses understanding, even when you realize you're also mourning your loneliness, and the inevitability of it. Judge — Scott Turow

Whatever is within your limit, do it to lift the souls of humankind. — Lailah Gifty Akita

For those moments, life is worth living. Moments of kindness, caring, and loving. — Debasish Mridha

It gives a thrill to life," he explained to me, "when life is carried in one's hand. Man is a natural gambler, and life is the biggest stake he can lay. The greater the odds, the greater the thrill. Why should I deny myself the joy of exciting Leach's soul to fever-pitch? For that matter, I do him a kindness. The greatness of sensation is mutual. He is living more royally than any man for'ard, though he does not know it. For he has what they have not - purpose, something to do and be done, an all-absorbing end to strive to attain, the desire to kill me, the hope that he may kill me. Really, Hump, he is living deep and high. I doubt that he has ever lived so swiftly and keenly before, and I honestly envy him, sometimes, when I see him raging at the summit of passion and sensibility. — Jack London

People will always notice something about you. It might be the way you walk or the way you talk, or just simply your personality. Live each day in the way you want to be remembered. Live in such a way that people will be inspired by those unique qualities that you have and strive to live better lives for themselves. — Amaka Imani Nkosazana

The child must adapt to ensure the illusion of love, care, and kindness, but the adult does not need this illusion to survive. He can give up his amnesia and then be in a position to determine his actions with open eyes. Only this path will free him from his depression. Both the depressive and the grandiose person completely deny their childhood reality by living as though the availability of the parents could still be salvaged: the grandiose person through the illusion of achievement, and the depressive through his constant fear of losing "love." Neither can accept the truth that this loss or absence of love has already happened in the past, and that no effort whatsoever can change this fact. — Alice Miller

1. Mahabharata (3.281.34) 34. adrohah sarva-bhuteshu karmana manasa gira anugrahas cha danam cha satam dharmah sanatanah Never displaying malice towards any living being through actions, thoughts or words, acts of kindness, and giving in charity; this is the Sanatana Dharma adhered to by righteous persons. — Hanuman Dass

Humility makes us more friendly
Happiness makes us more lively.
Love makes us more caring
Dream makes us more daring.
Trust makes us more forgiving
Kindness makes us more loving.
Hope gives us the joy of dreaming
Peace gives us the joy of living. — Debasish Mridha

The true purpose of life is the perfection of humanity through individual effort, under the guidance of God's inspiration. Real life is response to the best within us. To be alive only to appetite, pleasure, pride, money-making, and not to goodness and kindness, purity and love, poetry, music, flowers, stars, God and eternal hopes, is to deprive one's self of the real joy of living. — David O. McKay

I lived in the city of light for 4 years 10 months, the generosity of sacred souls sustain my livelihood. — Lailah Gifty Akita

People will not remember what you did for living,
they will remember how you touched them with kindness and loving. — Debasish Mridha

Living in the modern age, death for virtue is the wage. So it seems in darker hours. Evil wins, kindness cowers. Ruled by violence and vice we all stand upon thin ice. Are we brave or are we mice, here upon such thin, thin ice? Dare we linger, dare we skate? Dare we laugh or celebrate, knowing we may strain the ice? Preserve the ice at any price? — Dean Koontz

Through mindfully practising love and compassion we are able to heal our hearts and minds from our hurt and suffering, thus bringing harmony into this world. The more we are open to love, the easier it is to share kindness with all living creatures. — Christopher Dines

May our hearts be filled with great love for one another. — Lailah Gifty Akita

Take away religion, take away philosophy, take away the higher aims of art, and you deprive ordinary people of the ways in which they can represent their apartness. Human nature, once something to live up to, becomes something to live down to instead. Biological reductionism nurtures this 'living down', which is why people so readily fall for it. It makes cynicism respectable and degeneracy chic. It abolishes our kind, and with it our kindness. — Roger Scruton

Rise flexibly, courageously and perseveringly upon the challenges and trials in our life. Beneath the depth of fresh wounds, heavy cross and years of scars, is our wise silent mind, a beating faithful heart with understanding and patience matched with a humble soul who walks with hope towards charity, kindness, peace and harmony. — Angelica Hopes

Everyone you meet is hurt, broken and fighting a hard battle. Please don't be an ass. — Sarvesh Jain

Home is the dearest spot on earth, and it should be the centre, though not the boundary, of the affections. — Mary Baker Eddy

These dogs are not machines, goddamnit. They are alive! They are living, feeling, warm-blooded creatures of God, and they will love you with all their hearts! They will love you when your wives and husbands sneak behind your backs. They will love you when your ungrateful misbegotten children piss on your graves! They will see and witness your greatest shame, and will not judge you! These dogs will be the truest and best partners you can ever hope to have, and they will give their lives for you. And all they ask, all they want or need, all it costs YOU to get ALL of that, is a simple word of kindness. — Robert Crais

Taught by centuries of
living, the republic of immortal men had
achieved a perfection of tolerance, almost of
disdain. They knew that over an infinitely long span of time, all things happen to all men. As
reward for his past and future virtues, every
man merited every kindness - yet also every
betrayal, as reward for his past and future
iniquities. — Jorge Luis Borges

{Letter from Debbs to Eva Ingersoll, husband of Robert Ingersoll, just after the news of Robert's death}

We were inexpressibly shocked to hear of the sudden death of your dear husband and our best loved friend. Most tenderly do we sympathize with you, and all of yours in your great bereavement... Gifted with the rarest genius, in beautiful alliance with his heroism, his kindness and boundless love, he made the name of Ingersoll immortal.

To me, he was an older brother and as I loved him living, so will I cherish his sweet memory forever. — Eugene V. Debs

Societies in which most people depend for most of their goods and services on the personal whim, kindness, or skill of another are called underdeveloped, while those in which living has been transformed into a process of ordering from an all-encompassing store catalogue are called advanced. — Ivan Illich

Live in peace and harmony with all people. — Lailah Gifty Akita

Cherish kindness, even when you are living in wilderness. — Debasish Mridha

A spiritual retreat is medicine for soul starvation. Through silence, solitary practice, and simple living, we begin to fill the empty reservoir. This lifts the veils, dissolves the masks, and creates space within for the feelings of forgiveness, compassion, and loving kindness that are so often blocked. — David A. Cooper

A belief in a policy of kindness, and a sense of commonality among all living creatures. — Dalai Lama XIV

Let no one ever come to you without leaving better and happier. Be the living expression of God's kindness: kindness in your face, kindness in your eyes, kindness in your smile. — Mother Teresa

History is so comprehensive and detailed. I couldn't be a history student. I thought there was a time when I couldn't be a history maker, because of my limited understanding of what that meant. Today, thinking about the passing of Julian Bond and a wonderful conversation with a woman who has influenced so much, I think we all are history makers. All of our names will not be as known as Mr. Bond's or in books, but our names will be on someone's tongue and our memories will be in someone's heart, and we will all be a part of someone's personal story. We have a unique opportunity at this very second to change how we affect someone's life as living history and historians. Flaws and all. Yep. — Robin Caldwell

Give joy, smiles, happiness, goodness and kindness to every person you meet. — Lailah Gifty Akita

Buddhism is more a philosophy for living rather than a religion or dogma - it's about being awake, free from illusions and fear, so that compassion and loving kindness permeates all of our relationships. — Charlotte Kasl

We've made it private, contained it in family, when its audacity is in its potential to cross tribal lines. We've fetishized it as romance, when its true measure is a quality of sustained, practical care. We've lived it as a feeling, when it is a way of being. It is the elemental experience we all desire and seek, most of our days, to give and receive. The sliver of love's potential that the Greeks separated out as eros is where we load so much of our desire, center so much of our imagination about delight and despair, define so much of our sense of completion. There is the love the Greeks called filia - the love of friendship. There is the love they called agape - love as embodied compassion, expressions of kindness that might be given to a neighbor or a stranger. The Metta of the root Buddhist Pali tongue, "lovingkindness," carries the nuance of benevolent, active interest in others known and unknown, and its cultivation begins with compassion towards oneself. — Krista Tippett

Not only are we going to shift in our own lives - away from always trying to identify ourselves on the basis of what we have, what we do, and who we are better than, and so on - but shift into more reaching out, more service, more kindness, more living the virtues that Lao Tzu spoke about twenty-five hundred years ago. — Wayne Dyer

If you can cut yourself - your mind - free of what other
people do and say, of what you've said or done, of the things
that you're afraid will happen, the impositions of the body
that contains you and the breath within, and what the whirling
chaos sweeps in from outside, so that the mind is freed from
fate, brought to clarity, and lives life on its own recognizance
- doing what's right, accepting what happens, and speaking
the truth
If you can cut free of impressions that cling to the mind,
free of the future and the past - can make yourself, as
Empedocles says, "a sphere rejoicing in its perfect
stillness," and concentrate on living what can be lived
(which means the present) ... then you can spend the time
you have left in tranquillity. And in kindness. And at peace
with the spirit within you. — Marcus Aurelius
