Johnny Lim asked the following questions:
“Is the famous Schrodinger’s Cat experiment trying to depict this phenomenon of Quantum Superposition?”
It is a bit different. It involves the decay of a radioactive substance, even though some people try to make a connection.
“Are rupa kalapas a cocktail mixture of satara mahā bhūta?”
Yes. That is what is described in the post (specifically #2 and #12, among others).
“I know of some Theravadins who taught practitioners to discern rupa kalapas and the nature of satara mahā bhūta in order to discern ultimate materiality and mentality in order to fully penetrate the first Noble Truth…”
That is not possible. Rupa kalapas are formed within a billionth of a second and only a Buddha can discern such things.
In order to discern the ultimate materiality and mentality (or the nature of matter) one needs to have the yathabhuta nana (even that is not necessary if one comprehends the anicca nature, which CAN BE also be realized without knowing about the ’theory”). The new post on yathabhuta nana provides the theory.
