One fact which must be appreciated for applying this theory is the essential individual uniqueness of each of our minds, of each of our brains. It is no easy work to analyze either one's self or someone else. This theory is not, cannot be, a miracle key to a given human mind. It is devilishly hard work digging up enough of the basic facts and enough of the basic programs and metaprograms controlling each mind from within to change its poor operations into better ones. This theory can help one to sort out and arrange stored information and facts into more effective patterns for change. But the basic investigation of self or other selves is not easy or fast. Our built-in prejudices, biases, repressions and denials fight against understanding. Our Unconscious automatically controls our behavior. Eventually we may be able to progress farther. It may take several generations of those willing to work on these problems.
