The Karmapañjikā is a manual for the domestic rituals of the Paippalāda tradition. Claiming to follow a Sūtra of Paiṭhīnasi, the text was composed by an otherwise unknown Śrīdhara in Orissa in the 16th century ce. His work is a precious late-medieval witness to the Atharvavedic tradition, preserving archaic features dating from the Vedic period, but also showing much influence from various non-Vedic traditions that have been prevalent in this part of eastern India. The critical edition, which will be complete in three volumes, is based on six palm-leaf manuscripts written in Oriya script. This first volume contains an extensive introduction followed by the first nine chapters of text that describe the general paradigms of domestic ritual.
