The Supreme Personality of Godhead, Visnu, resides within the material world as the sattva-guna-avatara. Lord Siva is the tamo-guna-avatara, and Lord Brahma is the rajo-guna-avatara, but although Lord Visnu is among them, He is not in the same category. Lord Visnu is deva-deva, the chief of all the demigods. Since Lord Siva is in this material world, the energy of the Supreme Lord, Visnu, includes Lord Siva. Lord Visnu is therefore called jagad-vyapi, the all-pervading Lord. Lord Siva is sometimes called Mahesvara, and so people think that Lord Siva is everything. But here Lord Siva addresses Lord Visnu as Jagad-isa, the master of the universe. Lord Siva is sometimes called Visvesvara, but here he addresses Lord Visnu as Jagan-maya, indicating that even Visvesvara is under Lord Visnus control. Lord Visnu is the master of the spiritual world, yet He controls the material world also, as stated in Bhagavad-gita (mayadhyaksena prakrtih suyate sacaracaram [Bg. 9.10]). Lord Brahma and Lord Siva are also sometimes called isvara, but the supreme isvara is Lord Visnu, Lord Krsna. As stated in Brahma-samhita, isvarah paramah krsnah: [Bs. 5.1] the Supreme Lord is Krsna, Lord Visnu. Everything in existence works in proper order because of Lord Visnu. Andantara-stha-paramanu-cayantara-stham. Even paramanu, the small atoms, work because of Lord Visnus presence within them.
