At one time the Buddha was staying at Sāvatthī in the Jeta Grove, Anāthapiṇḍika’s Monastery. At that time Venerable Udāyī was staying in a beautiful dwelling in the wilderness. On one occasion a number of women came to the monastery to see the dwellings. They approached Udāyī and said, “Venerable, we would like to see your dwelling.” Then, after showing them his dwelling, he praised and disparaged their private parts; he requested and implored, asked and enquired, described, instructed, and abused their private parts. The shameless and indecent women flirted with Udāyī; they called out to him, laughed with him, and teased him. But after leaving, those of them who had a sense of shame complained to the monks, “Venerables, this isn’t suitable or appropriate. We wouldn’t want to hear such speech from our own husbands, let alone from Venerable Udāyī.”
The monks of few desires complained and criticized him, “How could Venerable Udāyī speak indecently to women?” They rebuked Udāyī in many ways and told the Buddha. The Buddha had the Sangha gathered and questioned Udāyī: “Is it true, Udāyī, that you spoke like this?” “It’s true, sir.” The Buddha rebuked him, “It’s not suitable, foolish man, it’s not proper, it’s not worthy of a monastic, it’s not allowable, it’s not to be done. How could you speak like this? Haven’t I given many teachings for the sake of dispassion, not for the sake of passion … the stilling of the fevers of worldly pleasures? This will affect people’s confidence …” … “And, monks, this training rule should be recited like this:
Final ruling ‘If a monk, overcome by lust and with a distorted mind, speaks indecent words to a woman, as a young man might to a young woman and referring to sexual intercourse, he commits an offense entailing suspension.’”
Definitions A: whoever … Monk: … The monk who has been given the full ordination by a unanimous Sangha through a legal procedure consisting of one motion and three announcements that is irreversible and fit to stand—this sort of monk is meant in this case. Overcome by lust: having lust, longing for, in love with. Distorted: a lustful mind is distorted; an angry mind is distorted; a confused mind is distorted. But in this case “distorted” refers to the lustful mind.
