sn.48.32 Saṁyutta Nikāya (Linked Discourses)

A Stream-Enterer

“Mendicants, there are these five faculties.
What five?
The faculties of pleasure, pain, happiness, sadness, and equanimity.
A noble disciple comes to truly understand these five faculties’ origin, ending, gratification, drawback, and escape.
Such a noble disciple is called a stream-enterer, not liable to be reborn in the underworld, bound for awakening.”
