I have 2 books and like 5 specialized papers on Buddhist self-mummification ,Sokojushinbutsu (sokushinbutsu is the mummy itself, not the practice)
Here is what a man who ,alone in the wilderness, wishes to mummify himself, should do:
>Diet of only nuts, roots, leaves, tree bark + exercise for 1, 2 years
>Use (thanks modern tech!) purgatives, diuretics, laxatives to rid the body of all filth
>approaching death: cut of all solid food, drink only salt and some water, put yourself in a closed room with like 200 incense sticks and candles
>death in like 2 weeks: Start drinking arsenic water and poison ivy tea, if possible fill your body with limestone my eating the stones, bury yourself in a small box full of charcoal and salt
