Sleep (Buddhism)

Sleep may be virtuous or non-virtuous. It is non-virtuous when it degenerates virtuous activity. The proper time for sleep is the middle watch of the night, when it should be with a desire to practice virtue and not motivated by affliction. It occurs when, powerlessly, the engagement of sense consciousness with objects is withdrawn inside.

One of the four changeable factors referred to in Tibetan Buddhism. These may be virtuous, non-virtuous or neutral depending on circumstances.
