Samadhi Talks

Samādhi (Pali and Sanskrit: समाधि), in the Indian religions, is a state of meditative consciousness. In many such traditions, the cultivation of samādhi through various meditation methods is essential for the attainment of liberation (nirvana, moksha) from the bondage to habitual desires, thought constructs, and unguarded behavioral patterns (fetters, samskaras), and the recognition of this liberated state as one's natural state or true 'self'.

In Buddhism, it is the last of the eight elements of the Noble Eightfold Path. In the Ashtanga Yoga tradition, it is the eighth and final limb identified in the Yoga Sutras of Patanjali. In Jain meditation, samadhi is considered one of the last stages of the practice just prior to liberation.

In the oldest Buddhist sutras, on which several contemporary western Theravada teachers rely, it refers to the development of an investigative and luminous mind that is equanimous and mindful. In the yogic traditions and the Buddhist commentarial tradition, on which the Burmese Vipassana movement and the Thai Forest tradition rely, it is interpreted as a meditative absorption or trance attained by the practice of dhyāna.
