"The heart, oddly enough, seems to be the essential organ concerned. When we are in a hurry or doing something we dislike, we clench the heart, exactly like clenching a fist, and nothing can get in. When we are filled with a sense of multiplicity and excitement we somehow 'open' the heart and allow reality to flow in. But in that state we only need to entertain the shadow of some unpleasant thought for it to close again. And human beings are so naturally prone to mistrust that it is hard to maintain the openness for very long. Children on the other hand find it easy to slip into states of wonder and delight when the heart finally opens so wide that the whole world seems magical. the 'trick' of the peak experience lies in this ability to relax out of our usual defensive posture and to 'open the heart'."

“And the central assertion of his philosophy is that this inner realm is the 'spiritual world' and that once man has learned to enter this realm, he realizes that it is not a mere imaginative reflection of the external world, but a world that possesses its own independent reality.”

“Taken as a whole, the Cross Correspondences and the Willet scripts are among the most convincing evidence that at present exists for life after death.

“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.”

“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.”

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