pasyadityan vasun rudran
asvinau marutas tatha
paçya—see; ädityän—the twelve sons of Aditi; vasün—the eight Vasus; rudrän—the eleven forms of Rudra; açvinau—the two Asvins; marutaù—the forty-nine Maruts (demigods of the wind); tathä—also; bahüni—many; adåñöa—that you have not heard or seen; pürväëi—before; paçya—there see; äçcaryäëi—all the wonderful; bhärata—O best of the Bhäratas.
O best of the Bhäratas, see here the different manifestations of Ädityas, Rudras, and all the demigods. Behold the many things which no one has ever seen or heard before.
Even though Arjuna was a personal friend of Kåñëa and the most advanced of learned men, it was still not possible for him to know everything about Kåñëa. Here it is stated that humans have neither heard nor known of all these forms and manifestations. Now Kåñëa reveals these wonderful forms.
