SB 2.1.34
isasya kesan vidur ambuvahan
vasas tu sandhyam kuru-varya bhumnah
avyaktam ahur hrdayam manas ca
sa candramah sarva-vikara-kosah
.
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
O best amongst the Kurus, the clouds which carry water are the hairs on His head, the terminations of days or nights are His dress, and the supreme cause of material creation is His intelligence. His mind is the moon, the reservoir of all changes.
