四分律比丘戒本 1.p38

1.p38

If a monk (monk) occupy a screened and sheltered place, in common with a woman, and sit in a spot fit for the commission of sin, and at the same time indulge in licentious (unlawful) conversation with her if, for example, she be a faithful lay woman (upāsika) and they converse together on matters relating to the three laws, viz., pārājika, saṅghādisesa, pācittiya; and if this monk, sitting in the manner mentioned, say of his own accord: “I have broken these laws, and am therefore liable to the several punishments attached to the transgression, whether entire exclusion, or suspension and penance, or public confession,” then according to what this faithful laywoman shall report, respecting the crimes which the monk has acknowledged, such shall be his punishment.
