"One simple method is to take a pen or pencil and hold it up against a blank wall or ceiling. Now concentrate on the pen as if it is the most important thing in the world. Then allow your sense to relax, so you see the pen against the background of the wall. Concentrate again. Relax again. Keep on doing this until you become aware of the ability to focus attention at will. You will find that this unaccustomed activity of the will is tiring; it produces a sense of strain behind the eyes. My own perception is that if you persist, in spite of the strain, the result is acute discomfort, followed by a sudden immense relief - the 'peak experience'."

“Man is as much a slave to his immediate surroundings now as he was when he lived in tree-huts. Give him the highest, the most exciting thoughts about man's place in the universe, the meaning of history; they can all be snuffed out in a moment if he wants his dinner, or feels irritated by a child squalling on a bus. He is bound by pettiness.”

“For Jung, the 'psychic world' was an independent reality, and it was possible to travel there and make the acquaintance of its inhabitants.”

“The unbeliever walks for a quadrillion miles, yet one moments of reality makes up for it.”

“Normally man’s mind is composed only of a consciousness of his immediate needs, which is to say that this consciousness at any moment can be defined as ‘’his awareness of his own power to satisfy those needs.’’ He thinks in terms of what he intends to do in half an hour’s time, a day’s time, a month’s time an no more. He never asks himself: what are the ‘’limits’’ of my powers? In a sense, he is like a man who has a fortune is the bank, who never asks himself, How much money have I got, but only, Have I enough for a pound of cheese, a new tie, etc.”
