1. Atthaka.-A celebrated sage, composer and reciter of sacred runes, mentioned together with nine others (Vāmaka, Vāmadeva, Vessāmitta, Yamataggi, Angirasa, Bhāradvāja, Vāsettha and Bhagu. Vin.i.245; D.i.104; DA.i.273), as the ancient rsis of the brahmins. They abstained from food at unseasonable times. They were the first teachers of the Tevijja Brahmins (D.i.238) and great sacrifices were conducted by them (A.iv.61).
Various teachings are attributed to them, e.g. that they recognised five kinds of Brahmins - brahmasama, devasama, mariyāda, sambhinnamariyāda, and brāhmanacandāla (A.iii.224ff). These sages did not claim to have discerned and realised the five qualities-truth, austerities, chastity, study and munificence - specified by the brahmins for the attainment of merit and the achievement of what is right (M.ii.199-200), though their followers behaved as if they did. Nor did they claim that they personally saw and knew that "here alone resides the truth and everything else is vain." (M.ii.169) In the Vimānavatthu Commentary it is said that the Buddha had realised those things of which these sages thought and for which they wished (p.265). (Brahmacintitan ti brahmehi Atthakādīhi cintitam, pañcacakkhunā dittham).
It is said that Atthaka and the other seers had the divine eye and had incorporated the teachings of Kassapa Buddha into their own scriptures. Thus (at that time) the three Vedas were in conformity with the Dhamma. But later the brahmins went back on these teachings (DA.i.273).
Atthaka is generally identified with Astaka mentioned as the author of Rg-veda x.104, unless the name be taken as a corrupt reading under which some representation of Atri may lurk. VT.ii.130, n.2.
2. Atthaka.-King. Mentioned in a list of kings who in times past had been unable to get beyond the domain of sense in spite of making great gifts and holding great sacrifices. J.vi.99.
3. Atthaka.-King. Mentioned in a list of former kings who had followed righteousness and who, by waiting diligently on ascetics and recluses, had gone to Sakka's heaven. J.vi.251.
4. Atthaka.-King. When Dandaka, having sinned against Kisavaccha, was destroyed with his realm, three of the subordinate lords within his kingdom - Kalinga, Atthaka and Bhīmaratha - went to consult the Bodhisatta Sarabhanga on the fate of Dandaka and his fellow-sinners. Their doubts were set at rest, and at the end of Sarabhanga's discourse they became free of their sensuality (kāmarāga) (J.v.135-49). Sakka himself was present at the interview and asked questions of Sarabhanga. See Sarbhanga Jātaka.
5. Atthaka.-Pacceka Buddha. Mentioned in a nominal list. M.iii.70; Ap.i.107.
