The intelligent thinker always asks sooner or later, "What is on the other side of death?" To the materialist, who believes in the brain as the only factor of perception, there is no hereafter. To those who believe in tradition, there is another life, but mostly they are very vague as to its real meaning. For those who are seeking the truth there is a right way and a wrong way of finding out about it. The right way consists in the study of the self, and the wrong way is in seeking to communicate with spirits.
