Kāḷaka untranslated

Kāḷaka 01. A seṭṭhi of Sāketa. His son was the husband of Cūḷa Subhaddā (q.v.) and therefore son-in-law of Anāthapiṇḍika. Kāḷaka was a follower of the Nigaṇṭhas. When the Buddha visited Sāketa, at the request of Cūḷa Subhaddā, Kāḷaka listened to his sermon and became a Sotāpanna. He gave his park, the Kāḷakārāma, to the Buddha, and built a vihāra there after removing, by force, the Nigaṇṭhas, who were in possession.

AN­a.ii.482f; but see Dhp­a.iii.465f, where the seṭṭhi’s name is given as Ugga of Uggapura; see also Divy.402, where the name of the city is Puṇḍavardhana and that of Anāthapiṇḍika’s daughter Sumāgadhā.

Kāḷaka 02. Senāpati of King Yasapāṇī of Benares, a previous birth of Devadatta. The story is given in the Dhammaddhajajātaka. Ja.ii.186ff.

Kāḷaka 03. See Ayyakāḷaka.

Kāḷaka 04. See AN.v.164, Sutta No. lxxxvii. Is Kāḷaka here a proper name or a generic name (Kāḷakabhikkhu) meaning a wicked monk?

I am inclined to take it as the latter. See Kāḷakabhikkhusutta.
