Buddhist mummy

[1] In 2015, the Hungarian Natural History Museum exhibited a Buddhist mummy hidden inside a statue of Buddha, during its first tour outside China.

Some monks like Tao Wing (道榮) or Yuet Kai (月溪) practised to get this after death.

1475 and whose body was retrieved relatively incorrupt in the 1990s, was achieved by the sophisticated practices of meditation, coupled with prolonged starvation and slow self-suffocation using a special belt that connected the neck with his knees in a lotus position.

[4] Some Shingon monks in Japan practiced Sokushinbutsu (即身仏), which caused their own death by adhering to a wood-eating diet consisting of salt, nuts, seeds, roots, pine bark, and urushi tea.

When the bell stopped ringing, the box would be dug up and treated as a buddha, granting favor provided it was preserved.
