190. [First Discourse on the Eye]
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: “If one does not discern and does not understand the eye, does not abandon and does not become free from desire for it, one is not capable of rightly eradicating dukkha.
“The ear … the nose … the tongue … the body … the mind is also like this.
“Monks, one who discerns and understands the eye, and who abandons and becomes free from desire for it, is capable of rightly eradicating dukkha. One who knows and understands the ear … the nose … the tongue … the body … the mind, and who abandons and becomes free from desire for it, is capable of rightly eradicating dukkha.”
When the Buddha had spoken this discourse, hearing what the Buddha had said the monks were delighted and received it respectfully.
