[ nitya , acc. to Senart used as synonym for nirvāṇa, Mv ii.140.16 ( vs ), see his note, comparing ii.144.4 . But this seems hardly sufficient evidence, and I have been unable to find elsewhere in Pali or BHS or Skt. any such use of nitya. Text: nityāntareṇa manasā kṛtamokṣabuddhiḥ, mārgaṃ (? mss. āryaṃ) va ( mss. ca) tāva mama putra cara prasīda, jīvāmi yāvac ca ahaṃ (so mss. ) …, (Śuddhodana pleads with the Bodhisattva to wait for his own death before renouncing the world; text in part uncertain;) with constantly internal mind fixing your will on salvation ( i.e. keeping it to yourself, not doing anything about it yet) … as long as I live … The word nitya, at any rate, seems to have its Skt. meaning.]
