Āsrava, “influx”, is the third Jain tattva. Like water through an open channel, karmic matter flows into the soul whenever it acts. Passion determines how strongly it binds. The Buddhist tradition uses a related word, āsava, for the taints of the mind, a sign of the shared vocabulary of the śramaṇa movements.
