The Nahāna Sutta (Rule on Bathing)
Background
This rule appears in the Vinaya Piṭaka, specifically in the Bhikkhunī Pātimokkha—the code of disciplinary rules for nuns. However, the principle applies equally to male monastics in the context of Theravāda traditions. The origin of this rule is connected to the living conditions of the monastic community during the time of the Buddha.
The middle Ganges region (Majjhimadeśa) was the cultural and religious center of ancient India, where the Buddha and his disciples spread the Dharma. The climate there was quite temperate, not as hot as in other regions. Therefore, the need for daily bathing was not as urgent as it might be elsewhere. This rule was established to prevent the tendency toward indulgence in comfort and convenience among certain monastics, thereby safeguarding spiritual purity and the cultivation of discipline.
Main Content
According to the Nahāna rule, a bhikkhunī (and likewise a bhikkhu) residing in the middle Ganges region may not bathe more than once every two weeks, except in cases of genuine necessity—such as when the body is dirty, fatigued, ill, or when external circumstances compel an earlier bathing. If this rule is violated without valid reason, the monastic must perform pāṭidesanā—a formal confession of wrongdoing.
Bathing here is not a matter of basic hygiene, but pertains to one's psychological attitude. The act of bathing frequently can arise from preoccupation with the body, infatuation with attending to outward appearance, or the craving for comfort and ease. These things stand in direct conflict with the spirit of practice—that is, the cultivation of inner relinquishment and the diminishing of wandering desires.
This rule also reflects the balance inherent in Buddhist discipline: it is not that bathing itself is unwholesome, but that excessive use of unnecessary things arises from greed and a loss of balance in one's way of life. Thus, the rule permits bathing when there is genuine need—dirt, illness, or exhaustion—while prohibiting bathing out of a fondness for comfort.
🌏 The Buddhist canon is vast — some sūtras (such as comparative Vinaya across schools, or untranslated Tibetan-canon texts) have to this day NEVER been translated into Vietnamese or English by anyone, scholars included. Rather than leave it blank, Inti AI offers a FAITHFUL summary grounded in the tradition — from the sūtra's title, origin and essence — so you can still reach this rare part of the treasury. Whenever an original translation exists, the app shows the original first.
