1. The BODY.
The ruling principle here is SIN: everyone was corrupted by sin and even believers today who are without sin nature present in them, are here on this level still subject to its promptings & mortality.
2. The MIND.
This in no way implies that those who live on the level of the body don’t use their mind but realm of dominance here is mind-power, logic, intellect, knowledge, morality.
The ruling principle here is the LAW.
This forms the second part of the two-part state called the FLESH.
And honestly It is relatively closer to the knowledge of God than just living to pleasure, but it is still far off on its own. Laws may compel people to act a certain way, but cannot make a person be good.
All human philosophies lie either in the first plane or mostly in this: philosophies of pain, indifference, wealth, gnostism, polytheism, monotheism, atheism.
For all have sinned.
Both form the state of being called FLESH.
3. The SPIRIT.
The ruling force here is the Spirit of God: here you’re raised to an elevated state, a new creature: beyond what sense living, or powerless idealistic living can give you.
