" The fire of devotion within the heart, ignited by the glance of the Beloved, contains the secret of divine consciousness, sirr allah. Sirr Allah is a spiritual substance within the innermost chamber of the heart, the heart of hearts. His divine consciousness, which reveals itself within the heart of His devoted servant. (p. 116) "
