n. act. to paritasyati, q.v. with discussion and references;
cf. Pali aparitassana, °nā), non-exhaustion, lack of discoura-
gement, not being wearied or troubled in spirit: aparita-
syanābhimukhenākhedacittotpādena (so ms., ed. em.
aparitrasya°) Śikṣ 25.7, not turned towards weariness
(note a-kheda-); aparitasyanatayā, ms. at Śikṣ 35.6 for
apariṇamanatayā which ed. reads with Gv 463.21 (the
source of the citation; see pariṇamana); nausamacittena
gamanāgamanāparitasyanatayā (so mss., ed. em. °trasya°,
without good reason) Śikṣ 35.9, with mind like a ship
because unwearied in going and coming; this is cited from
Gv 464.6 which reads parikhinnatayā, certainly an error
for aparikh°, a synonym of aparitasyana(tā), cf. akheda-
above on Śikṣ 25.7, and s.vv. paritasyati, °tras°.
Wogihara, Lex. 32 note 1, assumes that the original form
of these nouns contained °tasy° and that (a-)paritasana
(prec.) is a ‘purism’. This can hardly be assumed in view
of Pali paritasati beside °tassati, and BHS paritrasati
beside °syati.
