If the fire-pan were to break, let him pour that (fire in the pan) into any such unbroken, new pot with a wide mouth as there may be; for the pan which is broken indeed suffers injury, but uninjured is this deity (Agni): 'Uninjured I will bear him in the uninjured!' so he thinks. Into that (pot) he first throws a potsherd of the (broken) pan, and thus he (Agni) is not deprived of that womb of his.
