आगमे ब्राह्मे विश्वासटिप्पन्यः

And not also (can the expiation take place) prescribed in the chapter treating of qualification, because on account of the inference of his lapse from Smr̥ti he (the Naishṭḥika) is not capable of it.

If a Brahmacārin for life breaks from inattention the vow of chastity, is he to perform the expiatory sacrifice enjoined by the text, ‘A student who has broken the vow of chastity shall sacrifice an ass to Nirr̥ti [^sbe38251.htmfn_202]’ or not?

He is not, the pūrvapakshin says. For although in the chapter which treats of qualification (Pū. Mīm. Sū. VI, 8, 22) that expiatory ceremony has been settled (for Brahmacārins in general), it does not yet hold good for the professed Brahmacārin. For Smr̥ti declares that such sins cannot be expiated by him any more than a head once cut off can again be healed on to the body, ‘He who having once entered on the duties of a Naishṭḥika again lapses from them, for him–a slayer of the Self

I see no expiation which might make him clean again. ‘The Upakurvāṇa (i.e. he who is a Brahmacārin for a certain time only, not for life) on the other hand, about whose sin Smr̥ti makes no similar declaration, may purify himself by the ceremony mentioned.
