Orthodox Definition
Aniyata is a unique category in the monks’ Pātimokkha consisting of only two rules. It deals with situations where a monk is seen sitting alone with a woman in a secluded or private place, but the exact nature of what occurred is unknown.
Because the offense is “undetermined,” the Saṅgha relies on the testimony of a trustworthy laywoman (saddheyya-vacasā upāsikā)—famously exemplified by Visākhā, who inspired these rules. If the trustworthy laywoman claims the monk committed a Pārājika (intercourse), a Saṅghādisesa (lustful touching), or a Pācittiya (inappropriate speech), and the monk admits to sitting there, he is to be dealt with according to whichever offense he confesses to based on her accusation.
This category highlights the Vinaya’s practical approach to circumstantial evidence and the vital role of pure-hearted lay supporters in maintaining monastic integrity.
