sn.22.109 Saṁyutta Nikāya (Linked Discourses)
A Stream-Enterer
At Sāvatthī.“Mendicants, there are these five grasping aggregates.
What five?
That is, the grasping aggregates of form, feeling, perception, choices, and consciousness.
A noble disciple comes to truly understand these five grasping aggregates’ 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.”
