'Four kinds of Nirva^na.' In the teachings of the Yoga^ca^ra school， nirva^na is divided into four types. The first is the nirva^na of the originally pure self-nature， the original thusness of all existence. The second refers to the thusness expressed in the extinction of the hindrances due to defilement， and is called "nirva^na with remainder." The third is "nirva^na without remainder"; in this nirva^na the hindrances due to defilement in the mind are cut off， and the body in which the five skandhas was united is extinguished. In the fourth， both the hindrances due to defilement and the hindrances of knowing are cut off， and a deep wisdom is attained wherein sam!sa^ra and nirva^na are not distinguished. Not abiding in nirva^na nor disliking sam!sa^ra， one teaches sentient beings yet does not become attached to the world. This condition of complete separation from delusion is called "nirva^na with no abode."
