The country extending as far as the Eastern Ocean and as far as the Western Ocean, and lying between the same two mountains,—the learned know as ‘Āryāvarta.’ (22).

Medhātithi’s commentary (manubhāṣya):
The country that lies between the two limits of the Eastern and Western Oceans,—and between the two mountains spoken of in the preceding verse,—i.e., the Himālaya and the Vindhya,—is described as ‘Āryāvarta,’ ‘by the learned,’—i.e., by cultured people. It is called ‘Āryāvarta’ in the sense that the Āryas line there (‘Āryāḥ vartante tatra’); i.e., it is they that are born there again and again, and the Barbarians, even though attacking it repeatedly, do not remain there.

The particle ‘āṅ’ (in ‘āsamudrāt’) indicates the outer not the inner boundary, and it does not indicate inclusion. Hence the islands in the oceans do not come under ‘Āryāvarta.’

What are mentioned here are the four boundaries of the country: the Eastern Ocean on the east, the Western Ocean on the west, the Hiṁālaya on the north and the Vindhya on the south.

In as much as these two mountains have been mentioned as ‘boundaries,’ they are not included under ‘Āryāvarta’; from this people might be led to conclude that one should not inhabit these mountains. And with a view to (avoiding) this possibility, the Author adds the next verse.—(22)
