I check out Ansari of Herat. He was a sheikh who lived from 1006-1088.
Here is one of his poems, translated by Andrew Harvey.
Empty Me of Everything But Your Love | |||||
| Lord, send me staggering with the wine Of Your love! Ring my feet With the chains of Your slavery! Empty me of everything but Your love And in it destroy and resurrect me! Any hunger You awaken Can only end in Feast! |
