For me, we are all individuals with individual purposes/wills we all experience the universe in different ways. Therefore it follows nothing about divinity has to be universal in its application to individuals, However divinity contains everything so in a sense is universal but we would all experience it in different ways.
Well my experience of divinity is really beyond words, the closest I can get to is unity and harmony with everything, I don’t feel I would experience this without the divine.
Yes the mundane uses maths, science is probably the best way to explain the mundane and therefore maths is also an excellent way to explain the findings of science.
Numbers in the spiritual realm
are used in a variety of ways, as I’ve pointed out the cult of Pythagoras probably took this to the mot extreme, but things like Gematria are used to give another level of understanding. If you consider the phrase “let him who hath understanding reckon the number of the beast, for it is the number of a man his number is 666/616” is probably the most earthly and obvious take on this but there are whole books using Gematria to interpret the Bible - numbers have meaning 7 is completeness, 40 is to be cleansed etc etc. numbers are music which connect to the spheres etc. 12 is the connection of earth to the heavens.
im not saying any religions divinity is false,
saying all of them are true.
