FIRST KHANDHAKA(THE FORMATION OF THE ORDER OF BHIKKHUS)
Chapter-60 : Rules for Expulsion of Novices ; Sexual Intercourse .
At that time a novice, Kandaka by name, who was a follower of the venerable Upananda Sakyaputto, had sexual intercourse with a Bhikkhuni(Nun), Kandaka by name. The Bhikkhus were annoyed, &c.: 'How can a novice abandon himself to such conduct?'
They told this thing to the Lord Buddha.
'I prescribe, O Bhikkhus(Monks), that you expel a novice (from the fraternity) in the following ten cases: When he destroys life; when he commits theft; when he commits impurity; when he is a liar; when he drinks strong drinks; when he speaks against the Buddha; when he speaks against the Dhamma; when he speaks against the Sangha; when he holds false doctrines; when he has sexual intercourse with Bhikkhunis. In these ten cases I prescribe, O Bhikkhus(Monks), that you expel the novice (from the fraternity).'
