"That, as Nandana observes at this point (sloka 22), each country is given in the order of its authority, the best being first, is clear not only from the last verse, but from the one that follows it. For here it is stated that the ' district fit for sacrifice ' is all the country forming the natural habitat of the black buck, and this differs from the 'country of barbarians' in that the latter is not a place fit for the twice-born to live in. 'Natural habitat ' is not to be taken with the Commentators as making a distinction between country and town, but between the plains and the hills. The Gangetic plain and the country about Kuruksetra, between Delhi and Umballa and south of the former locality, is still the 'natural habitat' of the black buck. This account in Manu concludes with the words: " thus have I briefly expounded to you the home (yoni) of dharma, and its origin (sanmbhavta).""
