('Ayn al Yaqin). The Eye of Certainty. In the triad of the Knowledge of Certainty the Eye of Certainty the Truth of Certainty, the Eye of Certainty could be likened to actually seeing the light of the flames of a fire, after having merely heard a description of that fire. This is the stage of knowledge before being consumed by the flames themselves (Truth of Certainty). The Eye of Certainty is the inner eye or insight. The opening of this 'eye is a miracle and a mystery and it only comes about through the Mercy of the All Merciful. It is Allah's gift to His slave through His Infinite Grace. The seven levels of knowledge through which the traveller must pass on his Journey of Return to the Source are Surrender, Belief, Perfection; Knowledge of Certainty, Eye of Certainty and unconditional surrender with Knowledge.
(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.
(Nur) is the created light which radiates from the Uncreated Light of Allah. When this light enters the heart it drives away the existent order thereby annihilating the inner eye from witnessing 'other-than-Allah'. For unveiling to take place the Light which comes from Allah must coincide with the light within the heart. If there is darkness within the heart, then it will not be able to match the Light from Allah. In such a case there is no unveiling, and Knowledge of Allah does not arrive in that heart. It is the Remembrance of Allah which polishes the heart and allows it to be filled with light. The Source of this Pure Light is the Absolute Darkness of the Essence Itself. The most complete and penetrating light is the light through which is unveiled what Allah means by the forms seen by the imagination in dreams.
('Abd). The slave (and worshipper) is the one who is in a state of total and utter submission to the Will of Allah. After having been annihilated in Allah where all duality vanished and distinctions were erased, he returns to creation with perfect courtesy and with the Truth of Certainty that 'the Lord is the Lord and the slave is the slave'. When 'abd is translated as 'servant' it carries the implication that the servant can leave the service of his Master, if he so desires. However, the 'slave' is in total bondage, being utterly dependent upon his Master. All buying and selling transactions have been terminated. The slave belongs to Allah, completely, perfectly and unconditionally.
