In the sacred landscape of Sanatana Dharma, the relationship between the living and their departed ancestors (Pitrs) is considered profoundly sacred. Amavasya (New Moon Day) is the most significant tithi for performing Tharpanam (oblations of water and sesame seeds). For followers of the Yajurveda—one of the four principal Vedas—the procedure, mantras, and rituals for this act of gratitude are distinctly codified.
The word Tharpanam is derived from the Sanskrit root Trup, meaning "to satisfy" or "to please." It is an offering of water mixed with sesame seeds (til) and darbha grass, made to satiate the Pitrus (ancestors) and Devas (gods). Yajurveda Amavasya Tharpanam In Sanskrit Pdf
