MAHA-VISNU AND DURGADEVİ
The Supreme Lord says, "It should be understood that all species of life are made possible by birth in this material nature, and that I am the seed-giving father." Visnu impregnates mayà, the material nature, simply by glancing at her. This is the spiritual method. Materially we are limited to impregnating by only one particular part of our body, but the Supreme Lord, Krsna or Maha-Visnu, can impregnate by any part. Simply by glancing the Lord can conceive countless living entities in the womb of material nature.
The material nature is one of the energies of the Lord, and she can work under the direction of the Lord. When the Lord throws His transcendental glance over the material nature, then only can the material nature act, as a father contacts the mother, who is then able to conceive a child. Although it appears to the layman that the mother gives birth to the child, the experienced man knows that the father gives birth to the child. The material nature therefore produces the moving and standing manifestations of the material world after being contacted by the supreme father, and not independently.
