“[9-10] Let us approach that blazing Agni with animal and vegetable offerings, as cows hasten to their stalls. He has tossed about his flames (in every direction), like running streams of water; the rays comingle (with the radiance) visible in the sky.”

Caratha and vasthaya are explained as animal and vegetable offerings; further elaboration: tat prabhāvaiḥ bṛdayādibhiḥ sādhyāhutiḥ, paśuprabhāva-hṛdayādisādhanāyāhutya, these are invocations prompted by minds purified by offerings of moveable things, that is, animals; or of immoveable things, as rice, and the like
