In Part 1 of this series, I traced the quiet birth of the Upanishadic vision against the backdrop of one of humanity’s great turning points—the Axial Age. In Part 2, the focus turns to the Indian subcontinent itself—not yet Vedic, but already in motion. I will trace the social, political, and religious changes unfolding in pre-historic and proto-historic India, which together form the cultural soil from which later Vedic and eventually Upanishadic thought would emerge. I also show that evidence increasingly points to a profound continuity between the Harappan (Indus-Sarasvati) civilisation and later Indian culture, suggesting the Harappans themselves may have been the authors of the Rigvedic tradition that gave rise to the Upanishads.
