145. [Discourse on the Influxes and the Obstruction of Confusion]
Thus have I heard. At one time the Buddha was staying at Sāvatthī in Jeta's Grove, Anāthapiṇḍika's Park.
At that time the Blessed One said to the monks: “The existence of what is the cause, by clinging to what, by being fettered and attached to what, by seeing what as the self, do not yet arisen influxes, being obstructed by and burning with worry, sorrow, vexation, and pain arise, and already arisen influxes, being obstructed by and burning with worry, sorrow, vexation, and pain increase further?”
The monks said to the Buddha: “The Blessed One is the root of the Dharma, the eye of the Dharma, the foundation of the Dharma …” to be recited fully in the same way in the sequence of the above three discourses.
