Bu Pc 6262. Using water with living beings in it

Canon Rule 62: Using Water Containing Living Beings

Background

This rule is recorded in the Bhikkhu Pātimokkha, in the section on Pācittiya (offenses requiring confession), which is a collection of training rules for bhikkhus. According to the Theravāda tradition, these rules arose from specific situations that occurred during the training of the Sangha under the guidance of the Blessed One Gotama.

The rule concerning the use of water containing living beings (Sappāṇaka) is a concrete expression of the principle of Ahiṃsā (non-violence), one of the core ethical foundations of Buddhism. As bhikkhus live in populated areas or monasteries, they make regular use of water for daily needs. The question that arises is: how can one maintain personal cleanliness while also respecting the lives of the exceedingly small beings that dwell in water? This reflects a careful concern for moral causality (Kamma), which Buddhist teaching holds in high regard.

Main Content

According to the Pātimokkha, a bhikkhu who uses water containing living beings (such as microorganisms invisible to the naked eye) must acknowledge his offense by performing Pācittiya—a form of reviewing one's fault under the oversight of the Sangha or senior monastics.

This does not mean that bhikkhus are entirely forbidden from using water. Rather, the rule reminds them of the need for care and reflection before acting. Valid methods for using water are encouraged, such as employing strainers or filters to prevent the killing of living beings. Additionally, bhikkhus are advised to use water that has been boiled or rainwater (pristine water) so as to minimize risk.

The core principle here is that Sīla (virtue and precept) is not merely a matter of formal prohibitions, but is an expression of loving-kindness (Mettā) and respect toward all living beings. Whoever transgresses this rule must cultivate genuine remorse and commit to improvement in the future.
