Its evil to be overcome is the same, namely, transmigration; and its method of release is the same, namely _Buddhi_, or knowledge.

It is a more dialectic system than the others, and is rather of the nature of a logic than a philosophy.
Mr.Banerjea, in his Dialogues on the Hindu philosophy, considers the Buddhists' system as closely resembling the Nyaya system.

He regards the Buddhist Nirvana as equivalent to the emancipation of the Nyaya system.
Apavarga, or emancipation, is declared in this philosophy to be final deliverance from pain, birth, activity, fault, and false notions.

Even so the Pali doctrinal books speak of Nirvana as an exemption from old age, disease, and death.

In it desire, anger, and ignorance are consumed by the fire of knowledge.
