But, we may ask, as the world that we see has no reality, as it is an illusion, why do we see that illusion; what is the cause of that illusion which torments us? One uses the word "illusion" conventionally, but its true meaning is not realized until the reality of life is understood, until the innermost or eternal life is realized. It is when we understand this that everything seems an illusion; illusion is something which seems to exist but yet does not exist in any form. The nature of all things which seem to exist and do not last is like this: their existence is transitory, and to a certain extent the effect produced by them upon our soul is intoxication. We are so hypnotized by all we see, that momentarily we forget it is not lasting.
