And if any part of the sacrifice were to fail, let him make an oblation with regard thereto on the Âhavanîya during the consecration and the Upasads, and on the Âgnîdhra during the Soma feast--for whatever point of the sacrifice fails, that breaks--and whichever then is the deity in that (special offering), through that one he heals it, through that he puts it together again.
