ii. 2. The settings down in the Agnihotra must be explained. Having ladled out he sets down to the north of the Gārhapatya; thus he obtains this world. In the Āhavanīya (he sets down) for the second time when about to offer; thus he obtains the world of the atmosphere. After offering (he sets down) for the third time; thus he obtains yonder world.

That which he rubs the first time he smears on the mat; thereby he delights the plants; in that
