The practice of *Sokushinbutsu* represents one of the most extreme and fascinating rituals in the history of Buddhism. This rare and astonishing tradition, practiced by a select group of Japanese Buddhist monks, involves the ritual of self-mummification—an incredible process where individuals transform themselves into mummies while still alive, seeking to achieve enlightenment.

Dating back to the 11th century and predominantly observed in the mountainous regions of Northern Japan, *Sokushinbutsu* was performed by followers of the Shingon sect of Buddhism. These monks believed that through intense physical discipline, they could transcend human suffering and become living Buddhas, attaining eternal spiritual enlightenment.

For approximately 1,000 days, monks followed a rigorous diet known as *mokujiki*, meaning “eating a tree.” They consumed only nuts, seeds, bark, roots, and berries, drastically reducing body fat and muscle tissue. This harsh diet was aimed at purging the body of impurities and preventing decomposition.

In the next 1,000 days, monks would gradually introduce a toxic tea made from the *urushi* tree, which is also used to make lacquer. This substance served as a preservative by killing bacteria and parasites in the body, making it resistant to decay.

In the final stage, the monk would be sealed in a small stone tomb just large enough to sit in the lotus position. Equipped with only an air tube and a small bell, the monk meditated in darkness, ringing the bell daily to signal that he was still alive. When the bell stopped ringing, the tube was removed, and the tomb was permanently sealed.

After approximately three years, the tomb would be opened to determine if the monk had achieved *Sokushinbutsu*. Only a handful of monks successfully underwent the complete mummification process and were revered as living Buddhas. Those who did not fully mummify were still honored for their dedication and sacrifice.

Today, the preserved bodies of some *Sokushinbutsu* monks can still be seen in temples across Japan, serving as a testament to this extraordinary ritual of devotion, discipline, and the quest for enlightenment. This astonishing practice offers a profound insight into the lengths to which humans will go in their spiritual journey, reminding us of the incredible power of faith and the human spirit.
