tadAhiM
[ tadāhiṃ is apparently understood by Senart as meaning then in Mv ii.69.5 (prose), yadā bhagavāṃ pravṛttadharmacakro tadāhiṃ etaṃ bhikṣubhi śrutaṃ. But mss. tadā hi or tadā hi-m-( i.e. , I suppose, ‘hiatus-bridging’ m before following vowel); I think the particle hi must be assumed, after tadā. Perhaps Senart assumed a blend of tadā with (e)tar(a)hi(ṃ).]
