Bu Sk 4141. Opening the mouth

Exposition of the Anāhaṭa Sutta (Bu Sk 41)

Background

The Anāhaṭa Sutta is recorded in the Vinaya Piṭaka, specifically in the Suttavibhaṅga section of the Bhikkhunīvibhaṅga, belonging to the Theravāda Buddhist tradition. The title "Opening the Mouth" reflects an overarching rule concerning the conduct and discipline of bhikkhunīs (female monastics) in the early Buddhist Community.

The Vinaya Piṭaka is not merely a collection of punitive rules, but also an expression of the practice of mindfulness (sati) and adherence to the Dhamma. These rules were promulgated or approved by the Buddha to protect the purity of the Saṅgha, maintain internal harmony, and assist monastics in progressing along the path to liberation. In this context, the matter of "opening the mouth" carries profound significance with regard to the restraint of speech and its impact on the orientation of practice.

Main Content

The Anāhaṭa Sutta governs situations involving the utterance of improper words or disruptive actions, particularly in sacred circumstances or in the presence of the Buddha or venerable teachers. The term "anāhaṭa" (not prompted, not provoked) implies that a bhikkhunī should not speak words that are instigated or stirred up by unwholesome motives.

The specific content of this sutta within the Vinaya Piṭaka focuses on cases of transgression related to lack of restraint in speech, agitation, or saying unnecessary things at times when silence is called for. This relates directly to the five aggregates (pañcakkhandhā): formations (saṅkhāra), that is, the volitional impulses behind speech, belong to the group of phenomena conditioned by the mind and exert an influence upon mental development.

This rule also reflects the fundamental Buddhist principle of causality (kamma): every word is an act that bears consequences and is capable of producing results. Therefore, the restraint of speech is not merely a matter of discipline, but also a matter of cultivating wisdom (paññā).
