The monks heard it, and the monks of few desires complained and criticized him, “How could Venerable Udāyī act as a matchmaker for a brief affair?” They rebuked Udāyī in many ways and then told the Buddha. Soon afterwards he had the Sangha gathered and questioned Udāyī: “Is it true, Udāyī, that you did this?” “It’s true, sir.” The Buddha rebuked him … “Foolish man, how could you do this? This will affect people’s confidence …” … “And so, monks, this training rule should be recited like this:
Final ruling ‘If a monk acts as a matchmaker, conveying a man’s intention to a woman or a woman’s intention to a man, for marriage or for an affair, even if just a brief one, 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. Acts as a matchmaker, conveying: sent by a woman he goes to a man, or sent by a man he goes to a woman. A man’s intention to a woman: he informs a woman of a man’s intention. A woman’s intention to a man: he informs a man of a woman’s intention. For marriage: “You should be his wife.” For an affair: “You should be his mistress.”
