Uttarārcika

The Uttarārcika is the “Later Collection” of the Sāmaveda, presenting verses in expanded sāman form with melodic shaping and stobha insertions so they can be sung directly in Soma-yajña performance.

Soma—especially as Pavamāna, the purifying flow—and Indra in Aindra stutis. Soma hymns emphasize purification and ritual activation; Indra hymns emphasize victory, illumination, and empowering the sacrifice.

It provides performance-ready sāman expansions that are selected and organized within gāna traditions for specific ritual moments. In practice, it functions as a key source-text for what the Udgātṛ sings from the songbooks during Soma rites.
