You also asked in your letter to be told where Yashirō, who killed men, would be reborn in his next life. As sure as a needle sinks in the water and rain falls from the sky, a man who kills an ant falls to hell and a man who cuts off a dead body cannot avoid falling into the three evil regions of hell, hungry spirits, and beasts. Much more so, a man who kills a human. However, even a large boulder can float with the power of a boat, and a great fire can be extinguished with the power of water. Likewise, if a man does not repent for even a small transgression, he necessarily falls into an evil path, but if a man repents after committing a serious crime, his transgression will be expiated. There are many examples to support this.
