Following are the five types of people:

1. Nastik: One who does not believe in God.
2. Astik: For whom God exists.
3. Those for whom God also exists in them (I and the God are the same).
4. Tatvamasi: God not only exists in me but also in you.
5. Those who believe that God is in everybody.

People who believe that God exists are fearful people and they always fear God. People who see God in themselves, live a disciplined Satvik life and do not indulge in activities that are not God-friendly.

People who believe that God is not only in me but also in you, treat every person the same way as they treat themselves. People for whom God is everywhere always work for the welfare of the society.
