[49] Now at that time a certain bhikkhu engaged in sexual intercourse with a female monkey. He was remorseful, thinking: "A training rule (sikkhāpada) has been laid down by the Blessed One; could it be that I have committed an offense (āpatti) of pārājika?" He reported this matter to the Blessed One. "Bhikkhu, you have committed an offense of pārājika."
