Satapatha Brahmana Part V (SBE44), Julius Eggeling tr. [1900], at sacred-texts.com
11:2:4:11. The full moon, doubtless, is the same as that burning (sun), for he, indeed, is full day by day; and the new moon (darsa) is the same as the moon, for he appears (dars), as it were.
11:2:4:22. But they also say inversely, 'The full moon is the same as the moon, for after the filling up of the latter there is the night of full moon;' and the new moon (darsa) is the same as that burning (sun), for the latter appears, as it were.
11:2:4:33. The full moon, indeed, is this (earth), for she is, as it were, full; and the new moon is yonder sky, for yonder sky appears (or, is seen), as it were.
11:2:4:44. The full moon, indeed, is the night, for this
night is, as it were, full; and the new moon is the day, for this day appears, as it were. This, then, is the theory regarding the full and new moon in respect of the gods.
11:2:4:55. Then as to the body. The full moon is the up-breathing, for it is by the up-breathing 1 that this man is, as it were, filled; and the new moon is the out (and in)-breathing 2, for this out-breathing appears, as it were: thus, the full and new moon are these two, the eater and the giver of food.
11:2:4:66. The out (and in)-breathing (the mouth) is the eater of food, for by means of the out (and in)-breathing this food is eaten; and the up-breathing is the giver of food, for by the up-breathing 3 this food is given to him.
11:2:4:77. The full moon is the mind, for full, as it were, is this mind; and the new moon is speech, for this speech appears, as it were. Thus these two are clearly the full and new moon, as regards the body; and inasmuch as on the day of fasting he eats the (food) suitable for eating on the vow, he thereby clearly gratifies these two in regard to the body; and on the morrow (he gratifies them) as gods by sacrifice.
11:2:4:88. As to this they say,--'Seeing that no offering-material is taken out "for the full moon," nor any offering-material "for the new moon," and seeing that he does not say, "Recite the invitatory formula for the full moon," nor "Recite the invitatory formula
for the new moon;" nor "Recite the offering-formula for the full moon," nor "Recite the offering-formula for the new moon," how, then, is offering made to this full and new moon?' Well, when he makes a libation of ghee to the Mind--the full moon being the Mind--he thereby makes offering to the full moon; and when he makes a libation of ghee to Speech--the new moon being Speech--he thereby makes offering to the new moon: and thus offering is made by him to the full and new moon.
11:2:4:99. Now, some prepare two messes of rice, one for Sarasvat on the full moon, and one for Sarasvatî on the new moon, saying, 'We thus clearly make offering to the full and new moon.' But let him not do this; for Sarasvat is the Mind, and Sarasvatî is Speech; and thus, in making libations of ghee to these two, offering is made by him to the full and new moon: let him therefore not prepare these two messes of rice.
11:2:4:1010. As to this they say, 'Surely, he who performs the Full and New-moon offerings becomes a (mere) utterer of the Âgur 1; for, when he has performed
the Full-moon offering, he knows that he will perform the New-moon offering; and when he has performed the New-moon offering, he knows that he will again perform the Full-moon offering; thus when he goes to the other world he goes thither as an utterer of the Âgur: how, then, does he become one who has not (merely) uttered the Âgur?' Well, when, on both occasions, he makes those two libations of ghee (to Mind and Speech), then his Full and New-moon offerings become complete; and he goes to the other world after his Full and New-moon offerings are completed, and thus becomes one who has not (merely) uttered the Âgur.
31:1 The udâna is explained by Sâyana as the breath passing (up into the head, and) through the nose.
31:2 The prâna is the breath of the mouth.
31:3 That is, by (the vital air of) the head (hence of the eyes, ears, &c.).
32:1 Or, one who has only had the Âgur-formulas uttered for him (by the priests). Âgur is the technical term of two formulas, viz. of the formula '(Agnim) yaga' (recite the offering-formula to Agni, or to whatever deity offering is made), by which the Adhvaryu calls on the Hotri to recite; and of the formula 'Ye yagâmahe (Agnim),' by which the Hotri introduces the yâgyâ, or offering-verse. At the Soma-sacrifice the former formula is modified to 'Hotâ yakshat,' uttered by the Maitrâvaruna priest. See Haug, Transl. of Ait. Br., p. 133, note.--In comparing these Âgur-formulas with the performances of the Full and New-moon offerings, the author thus seems to imply that, just as the utterance of these formulas is merely the preliminary to the oblation itself, so each fortnightly p. 33 performance is only the preliminary to the next performance; but that the Sacrificer never actually completes the sacrifice. Sâyana, on the other hand, takes 'âgûrtin' to mean 'one who has formed a resolution (âgûrta, âguranam = samkalpa);' and native dictionaries, indeed, give 'âgur' as a synonym of 'pratigñâ' (promise, agreement; Zuruf, Zusage). But, even if this were the right meaning of the word, the general drift of the passage would remain the same, viz. that such a sacrificer would ultimately die as one who had merely promised or intended to offer sacrifice, without his having actually performed it, or brought it to a proper conclusion, and thus without reaping the ultimate benefit from it, viz. citizenship in the heavenly abodes.
