For by performing the Full-moon sacrifice at full moon, and the New-moon sacrifice at new moon, the gods forthwith dispelled evil, and were forthwith reproduced; and, verily, he who, knowing this, performs the Full-moon sacrifice at full moon, and the New-moon sacrifice at new moon, forthwith dispels evil, and is forthwith reproduced. If he offer an additional oblation, let him give a sacrificial fee (to the priests); for no oblation, they say, should be without a dakshinâ; and for the Full and New-moon sacrifices there is that dakshinâ, to wit, the Anvâhârya (mess of rice). Thus much as to the additional oblations; now as to (the sun) rising over him.
