“The earth is your vessel, the sky is your cover; I offer you into the mouth of Brahman; I offer you into the in-breath and out-breath of Brahmins endowed with learning. You are imperishable; may you not perish for the grandfathers in yonder world! The intermediate space is all around me; Vāyu is the listener to prevent negligence in what is given. The Yajus-formulas are your greatness!”
