The Sampuṭodbhava Tantra (Emergence from the Sampuṭa), also known as the Sampuṭodbhavaḥ or the Sampuṭa according to 84000,likely composed in the late tenth century, is a synthetic compendium of Buddhist tantric theory and practice. Drawing on about sixteen earlier sources—including foundational Father and Mother tantras like the Guhyasamāja—it treats nearly all aspects of advanced tantric thought. Framed as a dialogue between the Bhagavan (possibly either Cakrasaṃvara or Hevajra) and Vajragarbha, the discourse unfolds after the Bhagavan enters a specific samādhi. The term sampuṭa, denoting the enclosed space between two bowls, symbolizes the tantric union of wisdom and method, often interpreted as the nondual mind awakened through sexual yogic practice. (84000) The manuscript is in very good condition with clear lettering, making it easy to follow the contents.
