When ignorance has been destroyed, this identification ceases. Then bondage is at an end and the experiencer is independent and free.
Source: English translation of the Yoga Sutras of Patanjali (Swami Jnaneshvara Bharati)
By causing a lack of avidya, or ignorance there is then an absence of the alliance, and this leads to a freedom known as a state of liberation or enlightenment for the Seer.
