How Thought is imp'otent to divine the secret which the gods defend,
The Why of birth and life and death, that Isis-veil no hand may rend.
Eternal Morrows make our day; our is is aye to be till when
Night closes in; 'tis all a dream, and yet we die, — and then and then?
And still the Weaver plies his loom, whose warp and woof is wretched Man
Weaving th' unpattern'd dark design, so dark we doubt it owns a plan.

The Kasîdah of Hâjî Abdû El-Yezdî (1870)
