(Qaba Qawsayn). This term is also called 'Union of Union', or 'The Gathering of the Gathering'. It signifies one of the highest spiritual stations of Perfection which is attained by the greatest Perfect Men, that is, many of the Prophets of Allah and some of the great saints. This is the stage which immediately precedes absorption in the Source, Allah. It is the closest point that the slave can reach while still remaining the slave. It is that fine and inexpressible dividing line which separates Oneness from multiplicity, the Unseen from the visible, Allah from His slave.
(Wasl/Wusul). Union or joining. This term contains the idea of duality because of the joining, or union, between two. In complete union there is no duality whatsoever. Therefore, wasl is inferior to complete union. Through being the Divinity, Allah is perpetually in a state of wasl with engendered existence. "He is with you wherever you are" (The Qur'an 57:4).
(Jam' al Jam'). Gathering of the gathering. Jam' al jam' is the experience of union devoid of all distinctions, even of the idea of being one with Allah. This is the station of 'Two Bows' Length', the station of Perfection which is attained only by the greatest Perfect Men, who are the Prophets and the great saints. The Gathering of the gathering is also known as 'The Station of Great Glory'.
This is also Unity in Multiplicity. Annihilation in totality in Allah – in the Presence of the Divine Beauty. This is the opposite of farq (separation). This is Unity without separation. To gather that which belongs to Allah within you and surrender all of it to Him is real surrender. In the cosmos, there is nothing but Allah, His Names and His attributes. In short, this is called jama’. When we say jam’, it is the centre of multiplicity.
