SB 3.13.20
marici-pramukhair vipraih
kumarair manuna saha
drstva tat saukaram rupam
tarkayam asa citradha
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Struck with wonder at observing the wonderful boarlike form in the sky, Brahma, with great brahmanas like Marici, as well as the Kumaras and Manu, began to argue in various ways.
