(The mind's) dynamics transcend the time and space of brain physiology.

Mind is a kingdom to the man who gathereth his pleasure from ideas.

The mind, by its very nature, persistently tries to live forever, resisting age and attempting to give itself a form... . When a person passes his prime and his life begins to lose true vigor and charm, his mind starts functioning as if it were another form of life; it imitates what life does, eventually doing what life cannot do.

By the mind one is bound; by the mind one is freed. ... He who asserts with strong conviction: "I am not bound, I am free," becomes free.
