The Religion and Philosophy of the Veda and Upanishads v1.c18.s1.6

v1.c18.s1.6

Agni's brightness is often mentioned; he is like the sun, dispels darkness, and bears the epithet 'waking at dawn'. But, when he drives through the forest, shaving the earth like a barber a beard, his path is black. His flames roar terribly, and his light reaches the sky. But he has also a car drawn by two or more horses, with which he brings the gods to receive the offerings of men.
