Samādhi is the eighth limb of yoga and the goal of meditation in many Indian traditions: a state in which the distinction between meditator and object falls away and only the object shines. Patañjali distinguishes samādhi with and without support. In Buddhism, samādhi is concentration, the second of the three trainings.
