"Letting go doesn't mean we don't care. Letting go doesn't mean we shut down. Letting go means we stop trying to force outcomes and make people behave. It means we give up resistance to the way things are, for the moment. It means we stop trying to do the impossible--controlling that which we cannot--and instead, focus on what is possible--which usually means taking care of ourselves. And we do this in gentleness, kindness, and love, as much as possible." 

-Melody Beattie

“Emotional discomfort, when accepted, rises, crests and falls in a series of waves. Each wave washes a part of us away and deposits treasures we never imagined. Out goes naivete, in comes wisdom; out goes anger, in comes discernment; out goes despair, in comes kindness. No one would call it easy, but the rhythm of emotional pain that we learn to tolerate is natural, constructive and expansive. The pain leaves you healthier than it found you.” 
-Martha Beck

"To practice Zen Buddhism is to train oneself to eliminate hatred, anger, and selfishness and to develop loving-kindness towards all."

"Without the tao,
Kindness and compassion are replaced by law and justice;
Faith and trust are supplanted by ritual and ceremony."

"Kindness should become the natural way of life, not the exception."
-Buddha

"Kindness in words creates confidence. Kindness in thinking creates profoundness. Kindness in giving creates love."
-Lao Tzu
