Nigrodha Kappa Sutta
The twelfth sutta of the Cūḷa Vagga of the Suttanipāta.
Taught by the Buddha at Aggāḷava-
The Buddha says that Nigrodhakappa has won nibbāna, because he had severed all the bonds of Māra. Vaṅgīsa then declares that Nigrodha Kappa attained that state because he followed the Buddha’s teaching.
SN. pp.59ff; the verses of the sutta are included in the Theragāthā (1263‑79).
