'Hither are called the primeval, law-abiding, divine (fem.) heaven and earth, whose sons are gods.' He thereby calls to him those two, heaven and earth, within which all this (universe) is embraced.--'Hither is called this sacrificer:' thereby he calls the sacrificer to him. Why he does not mention his name on this occasion, is that this is a mysterious benediction on the idâ. Were he, on the contrary, to mention the name, he would do what is human, and the human certainly is inauspicious at the sacrifice: hence he does not mentionthe name, lest he should do what is inauspicious at the sacrifice .
