Samādhi, 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.
