All spiritual study is incomplete if it ignores the facts, truths, laws, and principles of cosmogony. To attempt to justify this neglect with the accusation that they belong to the world of illusion is silly and useless. For the accuser must still continue to live in an illusory body and use an illusory self governed by those laws. After every such attempt and for each violation of those laws--upon which the order and harmony of the universe depend--which his neglect brings about, he must pay the penalty in suffering.
