[Vâg. S. XIII, 19] 'For all breathing, out-breathing, through-breathing, and up-breathing;' for the naturally-perforated (brick) is the breath, and the breath serves for all that;--'for a resting-place, for a moving-place;' the naturally-perforated (bricks) are these worlds, and these worlds are the resting-place, the moving-place;--'May Agni guard thee'--that is, may Agni protect thee!--'with mighty well-being!' that is, with great well-being;--'with the safest roof,' that is, with whatever roof (abode) is the safest. Having 'settled' it, he pronounces the Sûdadohas on it: the meaning of this has been explained. He then sings a Sâman: the meaning of this (will be explained) further on.
