(Qalb). The human heart is the place of constant change and fluctuation. It is the supra-rational organ of intuition where the Transcendent Realities enter into contact with man. The heart is the isthmus between this world and the next. The battlefield of the Greater Holy War is the heart. This is where the downward-pulling lower self is confronted by the yearning spirit. The battle is fought between these two adversaries in order for one to take possession of the precious heart of man. Under the misguidance of the Misguider, the lower self wants the heart to plummet to the depths of ignorance. However, the spirit, which is from Allah, exerts a powerful attraction upon the heart, as it endeavours to guide it towards Knowledge of Allah. The greater the purification of the heart the more receptive it is to this irresistible attraction of the celestial spirit. The heart is the sanctified centre of man because it is the place which contains Allah. Keeping watch over the heart is part of the spiritual struggle of the Journey of Return. Those well-advanced along the Path never allow any intruders to enter their sanctified hearts. The heart of the Perfect Man is the Divine Throne around which circle the spiritual realities.
(Dhakir). The one who remembers Allah. The dhakir is precious to Allah Who created man only so that he would worship and know Allah. The one who turns, with an utter turning, towards fulfilling his reason for being, has been given the greatest gift from Allah Almighty.
(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.
(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.
(Lata'if). This term generally refers to the subtle essences (or centres) in the body. The cleansing of the subtle centres forms the spiritual struggle of the Path. The cleansing of each separate latifah marks a stage in the Journey of Return. Lata'if also defines the subtleties within the being of the knower and lover of Allah. The mystical vision during the spiritual concert prepares a thousand of these lata'if within the ecstatic.
