Bahá'u'lláh,
The Book of Ighan
(1915)
“ One is greatly astonished at such servants, who seek for proof after the banners of the proven are hoisted; who cling to the allusions of learning after the sun of the knowable hath appeared. It is like asking the sun for proof of its light, or the vernal shower for argument to demonstrate its bounty. The proof of the sun is its light which shines forth and encompasses the world; and the argument of the shower is its bounty which renews the world with a fresh mantle. Yea! The blind realize no effect in the sun but heat, and a barren soil knoweth no bounty from the vernal mercy. ”
