Samadhi

A form of meditation widely practiced in Theravada Buddhism in which the mind is concentrated on a single object and gradually calmed until only the object is known. The ultimate goal of this meditation is to enter the state of samadhi which is when the distinction between the object and the meditator disappears, which is the realization of non-dualism. This state is a prerequisite to entering the four levels of jhana and enlightenment.
