The mystic, P. D. Ouspensky, wrote that:

"[in] real art nothing is accidental. It is mathematics. Everything in it can be calculated, everything can be known beforehand.

The artist knows and understands what he wants to convey and his work cannot produce one impression on one man and another impression on another, presuming, of course, [they are] people on one level.... At the same time the same work of art will produce different impressions on people of different levels. And people from lower levels will never receive from it what people of higher levels receive.
