The microscopic living cell is more powerful than a volcano- the idea is more powerful than the geological cataclysm. - Petr Uspensky

Man is a machine, but a very peculiar machine. He is a machine which, in right circumstances, and with right treatment, can know that he is a machine, and having fully realized this, he may find the ways to cease to be a machine.
First of all, what man must know is that he is not one; he is many. He has not one permanent and unchangeable “I” or Ego. He is always different. One moment he is one, another moment he is another, the third moment he is a third, and so on, almost without end.

It is only when we realize that life is taking us nowhere that it begins to have meaning.

Q. Why is it so difficult to control attention? A. Lack of habit. We are too accustomed to letting things happen. When we want to control attention or something else, we find it difficult, just as physical work is difficult if we are not accustomed to it.
