O Visnudatta, Pariksit Maharaja, the Supreme Personality of Godhead was pleased by the great sages at that sacrifice. Consequently the Lord decided to personally exhibit the method of executing religious principles (as observed by brahmacaris, sannyasis, vanaprasthas and grhasthas engaged in rituals) and also satisfy Maharaja Nabhi’s desire. Consequently He appeared as the son of Merudevi in His original spiritual form, which is above the modes of material nature.
