This material goodness is contaminated. Sometimes goodness is affected by ignorance and passion in the material . . . so when you are transcendental to this material goodness, that stage is called Vāsudeva stage. And Vāsudeva stage, that means God realization.
So there are three incarnation of guṇāvatāra, then manvantarāvatāra. Manvantarāvatāra means . . . there is seventy-one yugas. One yuga means about 4,300,000's of years. 4,300,000's of years, that makes a complete yuga. Such seventy-one yuga is the duration of a Manu. That is called Man . . . and each Manu is also an incarnation, manvantarāvatāra. And such Manu takes place, fourteen Manus take place, during one day of Brahma. So manvantarāvatāra.
Then yuga avatāra. Yuga avatāra . . . in each yuga, during that 4,300,000's of years, there are yuga avatāra. They are the incarnation. They come. They are called yugāvatāras. And then there is śaktyāveśa-avatāra. Śaktyāveśa-avatāra, they are counted just like Lord Buddha, Jesus Christ. They are counted amongst the śaktyāveśāvatāras. They are also incarnation of śaktyāveśāvatāra, powerful. In this way the Supreme Lord manifests all over the universes. There are innumerable universes, and some of His incarnation are working always.
