It is at this point in the philosophy that we must understand that Man has the potential to transcend his known or knowable self. This potential to transcend the known and access the unknown is movement from the coarse to the fine. This movement through the house from, "the coarse to the fine" and from, "the known to the unknown", elevates Man to the potential of an ascending being.
It is at this level of understanding we reintroduce the law of reflectivity as a tool to view reflectivity, the unknown aspects of the house by the reflection of the know. In other words physical food, physical energy, and physical movement can be reflected to the mental by movement through the coarse to the fine and would yield the question, "what is mental food", "mental energy" and "mental movement." This known thing, reflecting to a question, creates a continuum in The Two-Story House that allows for movement in the house.
At this point we have established that downstairs consists of the physcial body and the mental mind, which represent the coarse material aspects of Man and the known qualities of The Two-Story House. We have also established that the primary component of movement through the house is "reflectivity" from the "coarse to the fine." It should also be clear by this time that "coarse to the fine" indicates energy and that each domain is a type of energy.
