The mind that is cheerful in its present state, will be averse to all solicitude as to the future, and will meet the bitter occurrences of life with a placid smile.
It is perhaps just dawning on five or six minds that physics, too, is only an interpretation and exegesis of the world (to suit us, if I may say so!) and not a world-explanation.
Man, like the universe, is a machine. Nothing enters our minds or determines our actions which is not directly or indirectly a response to stimuli beating upon our sense organs from without.
A cup is useful only when it is empty; and a mind that is filled with beliefs, with dogmas, with assertions, with quotations is really an uncreative mind.
When your mind doesn't stir inside, the world doesn't arise outside. When the world and the mind are both transparent, this is true vision. And such understanding is true understanding.
Mind you, there is no value in learning. You are all mistaken in learning. The only value of knowledge is in the strengthening, the disciplining, of the mind.
