He spake, ‘If (it were to fail) in respect of the Rik, ye should take ghee by four ladlings and offer it in the Gârhapatya fire with 'Bhûh!' and if in respect of the Yagus, ye should take ghee by four ladlings and offer it in the Âgnîdhrîya--or in the Anvâhâryapakana in the case of a Haviryagña--with 'Bhuvah!' and if in respect of the Sâman, ye should take ghee by four ladlings and offer it in the Âhavanîya with 'Svar!' But if it should not be known (where the mistake has occurred), ye should make offering in the Âhavanîya after uttering rapidly all (the three sacred words): thus one heals the Rig-veda by the Rig-veda, the Yagur-veda by the Yagur-veda, and the Sâma-veda by the Sâma-veda;--even as one would put together joint with joint, so does he put together (the broken part of the sacrifice) whoever heals it by means of these (three sacred words). But if he heals it in any other way than this, it would be just as if one tried to put together something that is broken with something else that is broken, or as if one were to apply some poison as lotion to a broken part. Let him therefore appoint only one who knows this (to officiate as) his Brahman, and not one who does not know this.
