I believe the senses we have to perceive the world around us are higher dimensional, just as other higher dimensions I have discussed. Our senses are not defined by the first 3Ds, yet are measurable and/or used to measure. In the subjects of math, science, and nature we see 7's omnipresence; 7 colors of the rainbow, 7 notes of a scale, 7 hermetic principles, 7 directions of 4D geometry, 7 main parts of the body, 7 orifices of the human head, 7 continents, and the 7 seas. I believe there are also 7 cardinal senses to add to this category.
We all know the first 5 senses, as well as our 6th sense of intuition. IMO the main 7th sense we need in order for any other senses to exist is conscious awareness. Other proposed higher senses I have put in parentheses.
I believe these other higher senses are not cardinal senses because they are composed of the overlapping of some of the other 7 cardinal senses. If I am correct in my assumption of senses, we can add them to the long list of how prime 7 influences nature with it's omnipresence. It is our higher dimensional senses which provides us manners in which to perceive the reality we are within.
