[The third Âsvinî brick he lays down, with Vâg. S. XIV, 3], 'By thine own powers seat thee here, a holder of powers,'--that is, 'By thy own energy seat thee here;'--'in the gods’ favour for high joy!' that is, 'for the favour of the gods, for great joy;"--'be thou kind, as a father to his son!'--that is, 'As a father is gentle, kind, to his son, so be thou kind!'--'rest thou readily accessible with thy form!'--the form, doubtless, is the body: thus, 'rest thou with readily accessible body!'--'May the Asvins, the Adhvaryus, settle thee here!' for the Asvins, as Adhvaryus, did lay down (this brick).
