The Veda, the transcendent śāstra, subsumes all knowledge. - Sheldon Pollock

From among the complexities of NS analysis of the Urheimat question it is worth calling attention to the way the nineteenth-century view expressed by Schlegel was reversed: the original Indo-Europeans were now variously relocated in regions of the Greater German Reich; German thereby became the language of the core (Binnensprache), whereas Sanskrit was transformed into one of its peripheral, ‘colonial’ forms.

For one thing, Sanskrit literary culture was never affected by communicative incompetence, which began to enfeeble Latin from at least the ninth century. The process of vernacularization in India, in so many ways comparable to the European case, was nowhere a consequence of growing Sanskrit ignorance.

... there exist no good accounts or theorizations of the end of the cultural order that for two millennia exerted a trans-regional influence across Asia-South, Southeast, Inner, and even East Asia- that was unparalleled until the rise of Americanism and global English. We have no clear understanding of whether, and if so, when, Sanskrit culture ceased to make history; whether, and if so, why, it proved incapable of preserving into the present the creative vitality it displayed in earlier epochs, and what this loss of affectivity might reveal about those factors within the wider world of society and polity that had kept it vital.
