This material world is a manifestation of the three modes goodness, passion and ignorance, and the Supreme Lord, for the creation, maintenance and destruction of the material world, accepts three predominating forms as Brahma, Visnu and Sankara (Siva). As Visnu He enters into every body materially created. As Garbhodakasayi Visnu He enters into every universe, and as Ksirodakasayi Visnu He enters the body of every living being. Lord Sri Krsna, being the origin of all visnu-tattvas, is addressed here as parah puman, or Purusottama, as described in the Bhagavad-gita (15.18). He is the complete whole. The purusavataras are therefore His plenary expansions. Bhakti-yoga is the only process by which one can become competent to know Him. Because the empiric philosophers and mystic yogis cannot conceive of the Personality of Godhead, He is called anupalaksya-vartmane, the Lord of the inconceivable way, or bhakti-yoga.
