tasmāt tisras tisra eka ekasya haviṣo bhavanti / (Cāturmāsya)

there are three for each oblation. Moreover thus he discriminates the rite for the fathers from the rite for the gods. Now the fathers are at a great distance; verily he summons them with the first, brings them with the second, and offers with the third. In that he sacrifices at the end to Agni, bearer of the oblation, (it is because) the fathers are Sviṣṭakṛt's; therefore he sacrifices to him at the end. In that after invoking the sacrificial food and smelling it they do not eat it, (it is because they think) ‘The sacrificial food is cattle; let us not cast the sacrificer's cattle in the fire’. In that the Adhvaryu gives to the fathers, verily thus he delights the fathers. In that they cleanse themselves (in the place) where the filters are, and the waters are healing and medicine, verily thus at the end in the sacrifice are healing and medicine produced.

In that at the end having sacrificed he sacrifices with an Iṣṭi, (it is because) the Sākamedhas terminate in that; therefore at the end having sacrificed he sacrifices with an Iṣṭi. In that afterwards he sacrifices with the full moon offering, thus in the first half of the month he sacrifices with the Sākamedhas.

v. 7. In that from the fore-offerings and the after-offerings he leaves out the two for the strew, (it is because he thinks) 'The strew is offspring; let me not cast offspring in the fire.' They are six; the seasons are six; the fathers are the seasons; verily thus he delights the fathers. In that he offers the butter portions with the word 'living', verily thus he causes the sacrificer to live. In that there are three for each oblation, (it is because) there are three oblations, and he cuts off from them together; therefore
