(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.
('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.
(Adab) is spiritual courtesy and gracious behaviour of the Path and perfect refinement of words and deeds. Adab is giving each thing and each moment its proper due. The science of the higher teaching is based upon adab, which encompasses all of human life. It extends from right behaviour with regard to the Sacred Law (Shari'a), right behaviour with one's fellow travellers, proper conduct towards the teaching and one's teacher, and reaches to unceasing spiritual courtesy to Allah Himself. The proper courtesy towards the Law is to stay within its boundaries, the proper conduct with regards to good actions is to complete the action and disconnect from it. Adab with regard to the Real is knowing what belongs to oneself and what belongs to Allah.
Each moment and each situation has it's own adab. It has been said that the higher teaching is all adab and the greater your understanding and implementation of proper conduct is, the higher you are in the teaching.
(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.
