Samadhi

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.

The eighth and final step in Patanjali's eight limbs of yoga is Samādhi. It means "putting together" and is often translated as "integration" or "absorption."
