Mandala 10

Mandala 10 closes the Rig Veda with its most varied and, in places, most philosophically ambitious material, standing apart from the ritual-focused family books in tone as much as in date. Its Purusha Sukta, hymn 10.90, describes a cosmic being, Purusha, sacrificed by the gods to create the universe, the sun from his eye, the wind from his breath, and, in verses of enormous later social consequence, the four varna classes of Hindu society from different parts of his body, a passage cited for millennia both to justify and, especially in the modern period, to sharply criticize the varna and caste system as later practiced. Its Nasadiya Sukta, hymn 10.129, the so-called Hymn of Creation, opens with radical uncertainty rather than confident cosmology, "there was neither non-existence nor existence then," and ends by openly doubting whether even the gods know how creation began, "who then knows, who here will declare it," among the most quoted expressions of philosophical humility in any ancient religious text.

The mandala also includes the Nadistuti Sukta, praising the rivers of the region by name and providing historians one of their most valuable sources for reconstructing early Vedic geography, alongside a wedding hymn, funeral hymns, and a memorable lament spoken by a compulsive dice player mourning his ruinous gambling addiction.

Few passages in world scripture carry as much disputed later weight as the Purusha Sukta's varna verses, since traditional and much later Hindu social organization repeatedly invoked this single hymn as scriptural sanction for a division of society into priests, warriors, commoners and servants, a reading modern reformers, including B. R. Ambedkar and other 20th century critics of caste, forcefully rejected as either a late, self-interested interpolation serving priestly interests or a description twisted over centuries of practice far beyond anything the hymn's own cosmic, mythic register was meant to prescribe; the historical relationship between this Rig Vedic text and the elaborated caste system of later centuries remains a genuinely contested question among historians rather than a settled one.

The Nasadiya Sukta's open agnosticism about the origin of the universe has drawn admiration far outside Hindu tradition, cited by scientists, philosophers and comparative religion scholars alike as a strikingly early example of a religious text declining to claim certain knowledge about ultimate origins. Mandala 10's greater linguistic lateness relative to the family books is well established by internal grammatical evidence, and its broader thematic range, moving from cosmology to social order to grief and ordinary human vice, has made it, alongside Mandala 1, the part of the Rig Veda most read on its own terms by modern audiences approaching the text for its ideas rather than for liturgical use.
