'We know, O Agni, thy threefold three,'--Agni, Vâyu (wind), Âditya (sun), these are his three in three forms;--'We know thy manifold scattered sites,'--inasmuch as he (Agni) is here distributed many ways;--'we know thy highest name which is in secret,'--'the youngest,' that indeed is his highest name in secret;--'we know that source whence thou art come;'--the source, doubtless, is the (heavenly) waters, for from the waters he first came.
