Animals and mankind have the same depth of conditioning that gives them their reactions to current events. Both have many emotional contractions to deal with. People can do this more easily than animals. After an animal becomes afraid, no doctor can delete his memory of that event. Canceling memories cannot make him grow.
Likewise, canceling memories in the man or woman denies the cause of an area of contraction that needs to be dealt with. Man can find the cause, with his ability to do due diligence, and delete the non-aligned attitudes responsible for it. Making this a goal will lead you to the non-contracted "Beingness" of the Master within.
