Not surprisingly, pornography is one of the world’s biggest industries, and is constantly growing. What seemed to satisfy people a hundred years ago does not seem to satisfy people anymore. Dr. Michael Laitman relates the insatiable desire for pleasure with the growth and strengthening of the human ego, and explains why people search for pleasure and satisfaction.
