an.5.129 Aṅguttara Nikāya (Numbered Discourses)

Fatal Wounds

“Mendicants, these five fatal wounds lead to a place of loss, to hell.
What five?
Murdering your mother or father or a perfected one; maliciously shedding the blood of a Realized One; and causing a schism in the Saṅgha.
These five fatal wounds lead to a place of loss, to hell.”
