He purifies his company, and also his kindreds—seven higher (ancestors) and seven lower (descendants). he alone deserves this entire earth.—(105)

Medhātithi’s commentary (manubhāṣya):
He becomes the sanctifier of his company; ‘company’ stands here for a number of persons arranged in a particular order; this ‘he purifies,’ makes free from taint; i.e., all sinful men, by associating with him, become sinless.

‘Kindreds’—persons born in his own family ;—‘seven higher,’ those above him, the Father &c., and ‘seven lower,’ those that are to come, yet to be born.

He alone is entitled to receive the gift of this earth extending to the oceans; ‘knowledge of Dharma’ establishes a claim to become the recipient; hence it is that a full knowledge of Dharma is sought to be acquired.—(105)
