Anyone who in discussion relies upon authority uses, not his understanding, but rather his memory.

Miguel de Unamuno

Understanding comes when you investigate, when you enquire, when you search out, which requires care, consideration, thought, affection.

Krishnamurti,  Bombay 13th March, 1948

Live it

However little you understand, however tiny a part, live it completely - not superficially, but deeply, fully, as vitally, as intrinsically, as enthusiastically as possible. Then, like a flower in a garden, that very living spreads its perfume. You don't have to do propaganda for the jasmine. The jasmine itself does the propaganda; its beauty, its perfume, its loveliness, tells the story. When you have not that loveliness, that beauty, you do propaganda for it, but the moment you have understood a little, you talk about it, preach it, shout it; because of your own understanding, you help another to understand, and therefore understanding spreads more and more, it moves further and further afield.

Krishnamurti, Bombay 10th Public Talk 14th March, 1948

No secrets

I have no secrets to teach you, and if I tried you may well make fun of me. Anyway, how could any understanding that I have become your understanding.

Kuei-shan

Wisdom is understanding yourself

From 33rd verse of the Tao Te Ching:

One who understands others has knowledge;

One who understands himself has wisdom.

Mastering others requires force;

Mastering the self needs strength.

A Tao-orientated life focuses on understanding yourself, rather than on the thinking and behaviours of others. You shift from the acquisition of information and the pursuit of status symbols to understanding and mastering yourself in any and all situations.

Wayne Dyer in "Change Your Thoughts Change Your Life" page 160-161

What you judge you cannot understand

Do you want to change the world? How about beginning with yourself? How about being transformed yourself first? But how do you achieve that? Through observation. Through understanding. With no interference or judgement on your part. Because what you judge you cannot understand.

Anthony de Mello in "Awareness" page 37

Knowledge and understanding

The positive advantages of knowledge, work specifically to the disadvantage of understanding.

Jung in "The Undiscovered Self" page 6
