(Dhikrullah). Invocation of Allah through one of His Names or through His Words. The perfect dhikrullah, in which Allah becomes the seeing, the hearing, the speaking, the grasping of the one who remembers, is attained when every atom of the dhakir's being is absorbed and annihilated in the Remembrance of Allah. The dhakir becomes internally unified with the Absolute. Only then does Allah sit totally with the one who remembers Allah.
(Sirr). The secret or mystery is a subtle substance of Allah's Grace. It is the innermost consciousness, the point of secret communication between the Lord and His slave. It is the hidden place where Allah manifests His mystery to Himself.
(Asrar). The asrar are hidden within the depths of the inner consciousness. They pass between the purified centre of the emancipated soul (who is a true slave!) and his Lord. All of the secrets derive from the Holy Prophet Muhammad (May the Salutations of Allah be upon him and Peace) and the Divine Lights abound according to the purity of one's inner secret.
(Mujahadah). The spiritual struggle and endeavour against the passions and downward-pulling tendencies of the lower self. Mujahadah is the ceaseless combat called the Greater Holy War. The war is fought with the celestial weapons of the Remembrance of Allah. The mature ones of the Path, those who 'know Allah', say that mujahadah is child's play! The real work of Men is Divine Knowledge.
