2.276

Māṇikūṭarāja Bodhisattva said, “The correct path and the erroneous path are two. One who abides in the correct path does not distinguish, ‘This is erroneous, this is correct.’ To be free of these two is entering the dharma gate of non-duality.”
The eightfold correct [path] and the eightfold erroneous [path] are two. Abiding in the true mark, equal and without discrimination, is named non-duality.
