iti vyavasita vipras
tasya rajnah prajataye
iti—thus; vyavasitah—having decided; viprah—the brahmanas; tasya—his; rajnah—of the king; prajataye—for the purpose of getting a son; purodasam—the paraphernalia of sacrifice; niravapan—offered; sipi-vistaya—to the Lord, who is situated in the sacrificial fire; visnave—to Lord Visnu.
Thus for the sake of a son for King Anga, they decided to offer oblations to Lord Visnu, who is situated in the hearts of all living entities.
According to sacrificial rituals, animals are sometimes sacrificed in the yajna arena. Such animals are sacrificed not to kill them but to give them new life. Such action was an experiment to observe whether the Vedic mantras were being properly pronounced. Sometimes small animals are killed in a medical laboratory to investigate therapeutic effects. In a medical clinic, the animals are not revived, but in the yajna arena, when animals were sacrificed, they were again given life by the potency of Vedic mantras. The word sipi-vistaya appears in this verse. Sipi means “the flames of the sacrifice.” In the sacrificial fire if the oblations are offered into the flames, then Lord Visnu is situated there in the form of the flames. Therefore Lord Visnu is known as Sipivista.
