3 Processes for Going Back to Godhead
Everyone should be given a chance to take prasada and thus be induced to chant the holy names of Hare Krishna and also dance in ecstasy. By these three processes, although performed without knowledge or education, even even a dog went back to Godhead.

Materialistic Enjoyer
When a man is attached to material enjoyment, he is attached to many miserable conditions, but nevertheless he accepts his condemned position as one of happiness. Sense enjoyment is so strong for such a person that he cannot give it up, exactly as a worm in stool cannot give up the stool. From the spiritual point of view, when a person is too absorbed in material enjoyment, he is exactly like a worm in stool. Although such a position is utterly miserable to the eyes of liberated souls, the materialistic enjoyer is greatly attached to it.
