In the case of out­wardly lis­ten­ing to mu­sic, shape-giv­ing fac­ul­ties of our neu­ro­physi­ol­ogy pro­ject the outer re­al­ity of the re­sound­ing mu­si­cal per­form­ance onto the sur­face of our mind; through that, the sur­face of our mind as­sumes the struc­ture of the sound­ing com­po­si­tion, thus pro­duc­ing the in­ner re­flec­tion of the outer mu­si­cal re­al­ity.
This is the em­piri­cal method of know­ing re­al­ity in mu­sic as we mu­sic lis­ten­ers prac­tise it.

When we per­ceive the per­fect fun­da­men­tal vi­bra­tion of the ab­so­lu­te sound-sub­stance si­mul­ta­ne­ously, this cos­mic vi­bra­tion also en­ters our sense of hear­ing and raises it to a state of cos­mic per­cep­tion.
Now we are able to feel our mind, which func­tions with in­fi­nite flexi­bil­ity, and to draw from it the per­fect mu­si­cal ex­peri­ence in the ab­so­lu­te mu­si­cal force-field of the har­mony.

By in­ces­santly in­fus­ing our sense of hear­ing with the per­fect fun­da­men­tal vi­bra­tion of the ab­so­lu­te sound-sub­stance and by per­ceiv­ing it there all the time, we gain cos­mic con­trol over our sense of hear­ing.
