Liberation; literally, the "unbinding" of the mind from the mental effluents (see asava), defilements (see kilesa), and the round of rebirth (see vatta), and from all that can be described or defined. As this term also denotes the extinguishing of a fire, it carries the connotations of stilling, cooling, and peace. (According to the physics taught at the time of the Buddha, a burning fire seizes or adheres to its fuel; when extinguished, it is unbound.) "Total nibbana" in some contexts denotes the experience of Awakening; in others, the final passing away of an arahant.
"Beautifully taught is the Lord's Dhamma, immediately apparent, timeless, of the nature of a personal invitation, progressive, to be attained by the wise, each for himself." Anguttara Nikaya V.332
