PURPORT

Lord Maha-Visnu, who is resting in yoga-nidra on the Causal Ocean and creating innumerable universes by His breathing process, only temporarily appears in the mahat-tattva for the temporary manifestation of the material worlds. He is a plenary portion of Lord Sri Krsna, and thus although he is nondifferent from Lord Krsna, His formal appearance in the material world as an incarnation is temporary. The original form of the Personality of Godhead is actually the svarupa or real form, and He eternally resides in the Vaikuntha world (Visnuloka). The word mahatmanah is used here to indicate Maha-Visnu, and His real manifestation is Lord Krsna, who is called parama, as confirmed in the Brahma-samhita [5.1]:

isvarah paramah krsnah sac-cid-ananda-vigrahah
anadir adir govindah sarva-karana-karanam

"The Supreme Lord is Krsna, the original Personality of Godhead known as Govinda. His form is eternal, full of bliss and knowledge, and He is the original cause of all causes."

Thus end the Bhaktivedanta Purports of the Third Canto, Eleventh Chapter, of the Srimad-Bhagavatam, entitled "Calculation of Time, from the Atom."
