From the SuttaCentral translation:
[quote]“If, Rāhula, when reflecting you realize; ‘Now this action that I have done by mind is conducive to my own harm, to the harm of others, and to that of both, hence unskilful is this mental action entailing suffering and productive of pain,’—such mental actions of yours, Rāhula, should be loathed, abhorred and despised. Thus loathing, abhorring and despising, you should acquire restraint in the future.
13. Being a mental offence, Rāhula is not exhorted (as in the case of bodily, and verbal, action) to confess it to anyone.[/quote]
As remarked in the footnote to Ven. Nyanaponika’s translation, there is one notable difference in advice regarding mental unskillful deeds (“thought crimes”) that deviates from the otherwise repetitive enumeration pattern: namely, the Buddha does not recommend confession or disclosure in this case, but instead to feel abhorred and disgusted (and ashamed?) by it. This has always been the most intriguing and noteworthy twist in the sutta, which is why I noticed it.
I guess the translator for the SuttaCentral main version (Ven. Sujato, I suppose?) simply continued the repetitive pattern from before according to the same formula as for bodily and verbal actions, without checking the Pali for possible differences after that.
As a tangent here, I am asking myself at the moment (again), whether or not the sutta can be understood as the Buddha recommending to feel remorseful in this case, in response to Ven. Dhammanando’s implication here that he did not, because “remorse (kukkucca) is a hindrance and always unskillful”, but, IIRC, in some earlier thread long time ago, Ven. Dhammanando also mentioned some abhidhammic stuff about remorse being an example of “an unwholesome citta that can give rise to wholesomeness” or something like that, and in light of that I find that it makes sense that the Buddha might have recommended feeling remorseful in response to certain situations (deeds one committed, by body speech or mind).
Just to give some context. Maybe, if someone else has something to say about that, they could chime in on that thread on DhammaWheel.
