Medhātithi’s commentary (manubhāṣya):
This verse lays down the reward of Life-long Studentship.

‘Dissolution of the body’—renouncing of life;—‘till’—up to that time;—‘who serves’—attends upon—‘his Teacher’;—such a Brāhmaṇa—‘goes’ to the ‘abode’—place, mansion—‘of Brahman’—‘eternal’;—i.e., he does not return again to the cycle of births.

‘Forthwith,’—i.e., by an easy path; not by the roundabout way of passing through the lives of animals and men.

The word ‘Brahman’ here stands, according to the view of the Purāṇas, for the particular God with four faces; and his ‘abode’ is a particular place in Heaven; while according to the Vedanta standpoint,’ ‘Brahman’ is the supreme Self, and his ‘abode’ is that Self itself, i.e., becoming absorbed hereinto.—(244)
