What were some of these teachings? "Man, Know thyself!" For self knowledge - the knowledge of the higher spiritual Self - is the pathway of wisdom, of understanding, of light, of peace, of power; and it comes to man through self-forgetfulness, and self-forgetfulness is the knocking, the mystic knocking, at the door of the initiation-chamber of the temple. (Chapter 3)
