An analogy for low temporal density would be walking through air, while high temporal density would be like walking through water. In the water, one expends greater energy but still progresses more slowly. Even higher levels would produce solid flows like glaciers and plate tectonics. Lower levels would produce a rarefied plasma state. An objects resistance to motion through space is seen as inertial energy, while its resistance to motion through time is seen as its gravitational mass.
Conscious awareness differentiates the two .
The text is in a box on hundreds of individual pages. Each from a different angle, using a different symbolic language, and in different contexts, but all based upon the same basic concept. Trying to explain the translation from one form to another in a way that is consistent, coherent, and seamless, is considerably time consuming. Doing it in common English is even harder. Your questions help to illuminate better ways for us to explain this translation.
