Say: My creatures are even as the fish of the deep. Their life dependeth upon the water, and yet they remain unaware of that which, by the grace of an omniscient and omnipotent Lord, sustaineth their very existence. Indeed, their heedlessness is such that were they asked concerning the water and its properties, they would prove entirely ignorant. Thus do We set forth comparisons and similitudes, that perchance the people may turn unto Him Who is the Object of the adoration of the entire creation. Bahá’u’lláh, The Summons of the Lord of Hosts.
