``sā vai vāc sṛṣṭā caturdhā vyabhavat/
eṣv eva lokeṣu trīni,.paśusu turīyam/
yā pṛthivī7.sā agni7.sā rathantare/
yāntarikṣe sā vāyu7.sā vāmadevye/
yā divi sā āditye sā bṛhati sā stanayitnu7/

"Indeed, Speech, being created, unfolded fourfold.
Three [parts] in these very worlds, the fourth in cattle.
That which is on earth is in Agni, that in the Rathantara;
that which is in the intermediate space is in Vāyu, that in the Vāmadevya;
that which is in heaven is in Āditya, that in the Bṛhat, that in thunder.
