[Vâg. S. XIII, 5; Rik S. X, 17, 11] 'The drop leaped along the earth and sky;' the drop is yonder sun, and he leaps both to the sky and to the earth--thus (in rising) to that (sky), and thus (in setting) to this (earth);--'along this seat, and that which was afore;' that is, to this world, and to that one; or this (Âhavanîya altar) which is now being built, and that (Gârhapatya altar) which yonder was built before;--'(the drop) moving along the common seat;' for he (the sun) moves along that common seat;--'the drop I offer along the seven hotrâs;' the drop is yonder sun; and the seven hotrâs are the regions: he thus establishes yonder sun in the regions.
