The Householder who fails not towards these three would win the three regions, and rejoice in heaven, radiant in body, like a God.—(232)

Medhātithi’s commentary (manubhāṣya):
‘Who fails not’—who does not omit the servise; i.e., by serving these ‘he wins,’—makes his own, obtains mastery over—‘the three regions.’

‘The householder.’—It is when the son has reached the householder’s stage that his service becomes of great value to his parents and others; as by that time they become old.

‘Radiant.’—Shining, resplendent with his own effulgence. ‘Like a God,’—i.e., like the Sun.

‘Rejoices in heaven’—in the heavenly regions.—(232)
