Cessation (Nirodha Samapatti) is the 9th jhana in the series of meditative experiences and is considered the peak of the practice. Here, the mind experiences the gradual shutting down of consciousness because of the co-dependent factors of perception and feeling have gone. The mind gathers and consciousness thins away, resulting in a complete cessation of consciousness: like the flame goes out, resulting in total unconsciousness.
Despite the absence of consciousness and may seems like a corpse, the body still maintains vitality and warmth.
It would be interesting to concretely prove this by brain scan and heart monitor. Cessation is not the final awakening or enlightenment but marks a significant milestone in the process. Some school of thoughts provide certificate of nibana just because someone reported having experienced cessation once or a few times.
Going through multiple cessations helps cut the string of fetters. Cessation brings about permanent changes in the mind, like deleting constantly running programs and allowing and preparing the mind to function in the absent of a self.
Cessation is followed by NIbana, emptiness, which will be explored in the next video.
