But the worst about a self-element is that its presence is never dreamed of till it is got rid of. - Petr Uspensky

There is no question of faith or belief in all this. Quite the opposite,this system teaches people to believe in absolutely nothing. You must verify everything that you see, hear and feel. Only in that way can you come to something.

Thought does not grasp, does not convey, what is at times clearly felt. Thought is too slow, too short. There are no words and no forms to convey what one sees and knows in such moments. And it is impossible to fix these moments, to arrest them, to make them longer, more obedient for the will. There is no possibility of remembering what has been found and understood, and later repeating it to oneself. It disappears as dreams disappear. Perhaps it is all nothing but a dream.

We may have very good reason for saying that we are ourselves beings of four dimensions and are turned towards the third dimension with only one of our sides, i.e. with only a small part of our being. Only this part of us lives in three dimensions, and we are conscious only of this part as our body. The greater part of our being lives in the fourth dimension, but we are unconscious of this greater part of ourselves. Or it would be still more true to say that we live in a four-dimensional world, but are conscious of ourselves only in a three-dimensional world. This means that we live in one kind of conditions, but imagine ourselves to be in another.
