As referred to previously, the boar incarnation was manifested in two millenniums, namely Svāyambhuva and Cākṣuṣa. In both millenniums there was a boar incarnation of the Lord, but in the Svāyambhuva millennium He lifted the earth from within the water of the universe, whereas in the Cākṣuṣa millennium He killed the first demon, Hiraṇyākṣa. In the Svāyambhuva millennium He assumed the color white, and in the Cākṣuṣa 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.
