So working through an aspect would go something like, "Man needs food for his physcial body," like hamburger or steak. The reflection would be "man's mental mind needs food as well" and what kind of food does the mental need, how do you feed it and how does it respond, etc. etc.?
The idea is to explore the similarities of the Physical and the Mental Mind; and if you can understand how to take care of the Physcial in a balanced way then one can use reflectivity and have a better idea as to care for the Mental.
So, it is that we have some idea about the downstairs of Man, and that Man spends most of his life down stairs in the known and knowable. In other words Man's life is spent primarily in the domains of the Physical and the Mental Mind. This being said, we must understand that there is more to man than the known!
