楞伽阿跋多羅寶經註解 2.241

2.241

The doctrine of nirvāṇa has the erroneous and the correct; wishing to explain the correct, the Buddha first refutes the erroneous. Regarding the four kinds of nirvāṇa of the tīrthikas, their names and lakṣaṇas are as listed in the sūtra. Nirvāṇa is the fruit; the fruit is obtained through causes. Since their causes are erroneous, the fruit is also not correct; therefore, he says, "not [the Dharma] taught by me." The nirvāṇa taught by me is simply the cessation of the mind of discriminating consciousness. Because the tīrthikas' nirvāṇa is not separate from the spiritual self, and the spiritual self is precisely the discriminating consciousness, he refutes them directly by means of the cessation of the discriminating consciousness.
