Decadent Singularity

Sokushinbutsu
Here are the general steps that some monks who attempted Sokushinbutsu followed, although keep in mind that these actions are both illegal and highly dangerous:

Ascetic Preparation: The process begins with a strict ascetic regimen that involves years of physical and mental preparation. Monks would follow a rigorous diet and exercise routine, which often included eating a special diet of nuts and seeds to reduce body fat.

Reducing Body Fat: Monks would gradually reduce their body fat through diet and exercise to make their bodies less susceptible to decay.

Drinking Poison: Monks would consume a poisonous tea made from the sap of the urushi tree (Japanese lacquer tree) to induce vomiting and diarrhea, expelling bodily fluids and preventing decay.

Meditation and Prayer: Throughout this process, monks would meditate and pray in a small underground chamber, living in near-complete isolation.

Sealing the Chamber: When they believed they were close to death, they would seal themselves inside the chamber with only a small tube for air and communication.

Waiting for Death: The monk would wait for death to come, continuing to meditate until they passed away.

Discovery: After the monk's death, fellow monks would check the chamber, and if the body showed signs of preservation, they would consider it a successful Sokushinbutsu.
