There's That

On Page Seventy, Sayadaw reveals that the Buddha, in the Mahasatipattana Sutta taught three entrances to Nirvana, as 1) Color Kasinas meditation, 2) Repulsiveness meditation, and 3) Voidness of self (the 32 parts meditation). 

He starts with repulsiveness meditation, and says that one can use the 32 parts, or any part and he uses skeleton meditation as an example.

I think I get the basic idea.  I do at times resist repulsiveness awareness, choosing to rest in some belief of eternal beauty and health.  But repulsiveness awareness, I believe, is not to say that there is only decay, more so to bring awareness to delusion.

The heavy metal dudes know.
