(Ma'rifa) is a light which Allah casts into the heart of whomsoever He Wills. This is the true knowledge which comes through unveiling, witnessing and tasting. This knowledge is from Allah, it is not Allah Himself, because He Is Unknowable in His Essence. The triad on the Sufi Path of Return is comprised of Fear, Knowledge and Love. Fear leads to Knowledge which leads to Unconditional Love of Allah. It is said that spiritual struggle is child's play while ma'rifa is men's work.
(Talaqqa). Receiving the knowledge which descends upon the slave from Allah. Such a receiving is not a taking. The hands of the slave are upturned and opened in readiness to receive whatever Allah Wills to send. The hands should never reach forward in expectancy to take these gifts from Allah. The Divine Mercy pours down like rain. The drops fall into the opened hand. Grasping fingers cannot catch them.
(Suluk) is travelling or Wayfaring. Suluk is journeying along the Spiritual Path of Return to the Source. It is the methodical travelling, through the states and stations, under the direction of a Spiritual Master (Shaykh, Murshid). The one who travels is the salik. The advance of the slave towards Allah is really the advance of Allah towards His slave. "Verily, I desire them more than they desire Me" says the beautiful Hadith Qudsi.
