Cessations of consciousness in meditation: Advancing a scientific understanding of nirodha samāpatti.

Meditation practitioners report being able to induce a total absence of consciousness lasting up to seven days, known as cessation or nirodha samāpatti. Unlike sleep, individuals in this state cannot be woken by external stimulation, experience no sense of time or tiredness, and have a stiff rather than relaxed body. Emerging from cessation is said to produce profound effects such as sudden clarity, openness, and insights. This paper outlines the historical context, presents preliminary data from two labs, sets a research agenda, and provides an initial framework for understanding these experiences. It integrates classical Buddhist concepts of nirodha and nirodha samāpatti into current cognitive-neurocomputational and active inference frameworks of meditation.

Abstract

Absence of consciousness can occur due to a concussion, anesthetization, intoxication, epileptic seizure, or other fainting/syncope episode caused by lack of blood flow to the brain. However, some meditation practitioners also report that it is possible to undergo a total absence of consciousness during meditation, lasting up to 7 days, and that these "cessations" can be consistently induced. One form of extended cessation (i.e., nirodha samāpatti) is thought to be different from sleep because practitioners are said to be completely impervious to external stimulation. That is, they cannot be 'woken up' from the cessation state as one might be from a dream. Cessations are also associated with the absence of any time experience or tiredness, and are said to involve a stiff rather than a relaxed body. Emergence from meditation-induced cessations is said to have profound effects on subsequent cognition and experience (e.g., resulting in a sudden sense of clarity, openness, and possibly insights). In this paper, we briefly outline the historical context for cessation events, present preliminary data from two labs, set a research agenda for their study, and provide an initial framework for understanding what meditation induced cessation may reveal about the mind and brain. We conclude by integrating these so-called nirodha and nirodha samāpatti experiences-as they are known in classical Buddhism-into current cognitive-neurocomputational and active inference frameworks of meditation.
