A mountain cave in the Sītavana, near Rājagaha (D.ii.116). A conversation that took place there between Sāriputta and Upasena, just before the latter’s death, is recorded in the Saṃyuttanikāya. Upasena died of snake-bite (S.iv.40). The cave was used as a residence by monks who come to Rājagaha from afar (e.g., Vin.ii.76).

Buddhaghosa says (SA.iii.10) that the cave was so called because it was shaped like a snake’s hood. It was here that the Buddha met and taught Tissa (13), the rājā of Roruva. ThagA.i.200.
