vidurah uvaca—Sri Vidura said; tena—by Him; eva—certainly; tu—but; muni-srestha—O chief among the sages; harina—by the Personality of Godhead; yajna-murtina—the form of sacrifices; adi—original; daityah—demon; hiranyaksah—by the name Hiranyaksa; hatah—slain; iti—thus; anususruma—heard in succession.
Sri Vidura said: O chief amongst the great sages, I have heard by disciplic succession that Hiranyaksa, the original demon, was slain by the same form of sacrifices, the Personality of Godhead [Lord Boar].
As referred to previously, the boar incarnation was manifested in two millenniums—namely Svayambhuva and Caksusa. In both millenniums there was a boar incarnation of the Lord, but in the Svayambhuva millennium He lifted the earth from within the water of the universe, whereas in the Caksusa millennium He killed the first demon, Hiranyaksa. In the Svayambhuva millennium He assumed the color white, and in the Caksusa millennium He assumed the color red. Vidura had already heard about one of them, and he proposed to hear about the other. The two different boar incarnations described are the one Supreme Personality of Godhead.
