When the Supreme Personality of Godhead creates different types of bodies, offering a particular body to each living entity according to his character and fruitive actions, the Lord revives all the qualities of material nature—sattva-guna, rajo-guna and tamo-guna. Then, as the Supersoul, He enters each body and influences the qualities of creation, maintenance and annihilation, using sattva-guna for maintenance, rajo-guna for creation and tamo-guna for annihilation.
