Three can keep a secret, if two of them are dead.
-Benjamin Franklin
We should not say that one man's hour is worth another man's hour, but rather that one man during an hour is worth just as much as another man during an hour. Time is everything, man is nothing. He is at the most time's carcass.
-Karl Marx
Life is a maths equation. In order to gain the most, you have to know how to convert negatives into positives.
Don't be too timid and squeamish about your actions. All life is an experiment.
-Ralph Waldo Emerson
The guru cannot awaken you; all that he can do is to point out what is. The guru can give you words; he can give you an explanation, the symbols of the mind, but the symbol is not the real, and if you are caught in the symbol, you will never find the way.
As the heat of a fire reduces wood to ashes, the fire of knowledge burns to ashes all karma. Nothing in this world purifies like spiritual wisdom. It is the perfection achieved in time through the path of yoga, the path which leads to the Self within.
Happiness is your nature. It is not wrong to desire it. What is wrong is seeking it outside when it is inside.
-Ramana Maharshi
