"Wisdom tells me I am nothing. Love tells me I am everything. Between the two my life flows." 

-Nisargadatta Maharaj

“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

"Wisdom may be perennial, but to see its relevance we must see it lived out." 

-Eknath Easwaran

"The mind sees the world as a thing apart, And the soul makes the world at one with itself. A mirror scratched reflects no image— And this is the silence of wisdom." 
-Edgar Lee Masters

“We live thinking I am right, I am wise. Herein lies the cause of human delusion.” 
-Ko Kamei

“All truly wise thoughts have been thought already thousands of times; but to make them truly ours, we must think them over again honestly, till they take root in our personal experience.”
-Johann Wolfgang von Goethe

"Wisdom and compassion flow from simplicity and clarity; from having nothing to prove and nothing to defend." 

-Barry Magid

“A clear mind comes from the wonderful fundamental essence given us by nature and is not a personal possession. Impartiality beyond any specific culture fosters clarity and deeper seeing. It is not hard to produce wisdom…what is hard is to have wisdom not interrupted.” 

-Lao Tzu

"By three methods we may learn wisdom: First, by reflection, which is noblest; Second, by imitation, which is easiest; and third by experience, which is the bitterest."

-Confucius

"If you can give up your former knowledge and understanding, thus making your heart open, not keeping anything at all on your mind, so you experience a clear empty solidity where speech and thought do not apply, you will directly merge with the fundamental source, sinking into the infinite, spontaneously attaining inherent wisdom that has no attainment."
-Yuanwu

"As one lamp serves to dispel a thousand years of darkness, so one flash of wisdom destroys ten thousand years of ignorance."

-Hui-Neng
