The Sutta on Leaving Bedding Outside

Seyyasanthārana Pāṭimokkha — The Brahma Discipline

Background

The Sutta on Leaving Bedding Outside (Seyyasanthārana) is one of the prohibitions in the Pāṭimokkha, the collection of core ethical principles for bhikkhus in the Theravāda tradition. This rule arose from an event that occurred at Sāvatthī, where some monks often left beds, mattresses, cushions, blankets, and other sleeping requisites outside to sun or dry after washing. However, this action gradually became a form of negligence, a lack of responsibility toward the community’s property, and could damage the valuable requisites of the Sangha.

The Buddha, always observing violations of discipline among monks and nuns, issued this prohibition to protect both common property and the practice of mindfulness in the monastic path. This rule reflects a basic principle of the Buddha-Dharma: mindfulness, responsibility, and non-negligence in every action.

Main Content

The Seyyasanthārana Sutta states that bhikkhus may not leave bedding (seyyā), including mattresses, pillows, sheets, blankets, and other sleeping requisites, lying outside without anyone attending to them or without the intention to use them soon. Leaving these items exposed outside carelessly is considered a Pācittiya offense, whether unintentional or intentional, though not a grave act.

The rule does not prohibit airing mattresses to dry when necessary, but it requires initiative, responsibility, and mindfulness. A bhikkhu must have a clear purpose, must place them within a protected boundary, or must remain nearby to guard them. Carefree, inattentive, or unconscious conduct that leaves requisites forgotten outside is not permitted.

This rule also reflects carefulness in the use of common property. Each bhikkhu receives the requisites needed for the life of practice, but must preserve them responsibly, without excess and without negligence.
