Beauty in things exists in the mind which contemplates them. Everybody knows everything. If you think it's going to rain, it will. There is no purification in this world equal to wisdom. Bhagavad Gita .
Concentration is the ability to think about absolutely nothing when it is absolutely necessary.
Every vital organization owes its birth and life to an exciting and daring idea. Knowledge is telling the past. The definition of a genius is someone who knows more than you. To know that we know what we know, and that we do not know what we do not know, that is true knowledge. Genius is eternal patience.
