Lzh Mu Bu Vb Sk 37Na vikṣipya pādau niṣatsyāma

Explanation of the Na Vikṣipya Pādau Niṣatsyāma Sutta

Background

The Vinaya Piṭaka is a collection of regulations on ethics and discipline in the Sangha. The sutta Na vikṣipya pādau niṣatsyāma (“We should not sit with the legs thrown out”) appears in the Nissaggiya Pācittiya section, rules concerning offenses that require relinquishment and confession. These are details about conduct in the daily life of monastics, reflecting the profound purpose of Theravāda Buddhism: to train the mind through even the smallest actions.

The situation in this sutta concerns ordinary moments in the life of practice: how to sit, how to place the legs, matters that outwardly may seem trivial but contain deep meaning. These regulations are not arbitrary prohibitions, but guidance for monastics to train the mind and respect the discipline of the religious community.

Main Content

This sutta teaches that when sitting, monastics should not leave their legs sprawled loosely or extended outward. This action is considered lacking in dignity and not fitting for the status of one gone forth. The Buddha taught that discipline (vinaya) begins with every gesture and every breath. When one lets the legs sprawl outward in public, one displays negligence and loss of vigilance, and this directly affects the state of mind.

In Theravāda teaching, every bodily movement is connected with the state of mind. A loose sitting posture, with the legs sprawled outward, not only reflects lack of concentration but also gives a poor impression to those who see it, damaging respect for the Dharma. Therefore, the Buddha taught that monastics should sit in a stable posture, with the two legs kept neatly, expressing vigilance and dignity.

This rule is also related to the principle of “energy” (viriya, right effort), one of the factors of the Noble Eightfold Path. Intentionality in how one places the legs and how one sits is itself an expression of unceasing effort in practice.
