I was flipping through some of my books... I was trying to find some books that might interest you. Realities of Sufism by Shaykh Abd al Qadir Isa The Removal of Cares by Abdul Qadir Jilani The Basic Research by Ibn Ajiba The Darqawi Way by Darqawi Music of the Soul by Shaykh Muhammad Al Jamal Of the books that I think you will benefit the most from is probably the last two... But they all of stuff of the unseen.... And the last two books seem kind of random, in that it jumps around alot. I hope that helps...
