"The lover’s teacher is the Loved One’s beauty, His face their lesson and their only book."

...

"In this realm, instruction is assuredly of no avail.
The lover’s teacher is the Loved One’s beauty,
His face their lesson and their only book.
Learning of wonderment, of longing love their duty,
Not on learned chapters and dull themes they look.
The chain that binds them is His musky hair,
The Cyclic Scheme, 5 to them, is but to Him a stair. 6

Here followeth a supplication to God, the Exalted, the Glorified:

O Lord! O Thou Whose bounty granteth wishes!
I stand before Thee, all save Thee forgetting.
Grant that the mote of knowledge in my spirit
Escape desire and the lowly clay;
Grant that Thine ancient gift, this drop of wisdom,
Merge with Thy mighty sea. 7

Thus do I say: There is no power or might save in God, the Protector, the Self-Subsistent." 8

The Cyclic Theory of Abú-‘Alí Síná (Avicenna—980–1037) as expressed by him in the quatrain: Every semblance, every shape that perisheth today In the treasure-house of Time is safely stored away. When the world revolveth to its former place, Out of the Invisible He draweth forth its face. See also Some Answered Questions, p. 284.
