An Explanation of the Nisinno Sayanassa Sutta

Background

The Nisinno Sayanassa Sutta (Nisinna Sayanassa) is recorded in the Vinaya Piṭaka, specifically in the sections regulating the conduct of bhikkhus and bhikkhunīs in daily life. The context in which this sutta appeared is connected with practical situations that arose in the early Sangha, when the Buddha needed to establish clear rules to preserve discipline and proper deportment.

The title “Nisinno sayanassa” means “one who is sitting and one who is lying down” — referring to basic postures in Buddhist practice. This sutta belongs to the Pātimokkha, or the fundamental rules, which are the foundation of Vinaya study in the Theravāda Buddhist tradition.

Main Content

The sutta deals with regulations concerning the sitting and lying postures of monastics, especially in the context of meditative practice and observance of the Vinaya. These regulations are not arbitrary prohibitions, but reflect mindful choice (sati) and respectful discipline of the body.

In the Vinaya Piṭaka, sitting and lying down are regarded as two of the most basic postures. The sitting posture (nisinna) is commonly practiced during meditation, prayer, or diligent effort. The lying posture (sayana) is permitted during times of rest, but with certain restrictions concerning the manner and place of lying down.

The sutta points out that these postures should not be assumed carelessly. Sitting should be deliberate and alert; lying down should follow certain principles so as to avoid losing mindfulness or disturbing others. The detailed regulations include: one should not lie down in unsuitable places, should not lie down in undignified ways, and should maintain vigilance even while resting.

Practical Meaning

The Nisinno Sayanassa Sutta teaches that bodily discipline is not merely a matter of outward behavior, but an expression of mindfulness and respect for the Dharma. To manage one’s posture is to manage one’s mind.
