Samadhi

Samādhi (Sanskrit: समाधी, also called samāpatti), in Hinduism, Jainism, Buddhism, Sikhism, and yogic schools, is a state of meditative consciousness. In the yogic traditions, and the Buddhist commentarial tradition on which the Burmese Vipassana movement and the Thai Forest tradition rely, it is a meditative absorption or trance, attained by the practice of dhyāna.In the oldest Buddhist suttas, on which several contemporary western Theravada teachers rely, it refers to the development of a luminous mind which is equanimous and mindful.
Samadhi is the last of the eight elements of the Noble Eightfold Path. It is often interpreted as referring to dhyana, but in the suttas samadhi and dhyana are not the same. While samadhi is a one-pointed concentration, in dhyana this samadhi is used in the initial stages, to give way to a state of equanimity and mindfulness. The practice of dhyana makes it possible to keep access to the senses mindfully, avoiding primary responses to the sense impressions.
