大毘盧遮那成佛經疏 1.37

1.37

The sūtra says: “The yoga self.” This refers to practitioners of meditation who impute the principle of correspondence of this inner mind to be the true self, permanently abiding, unmoving, its true nature clear and calm; they hold that this alone is the ultimate path, free from cause and effect. Because they do not contemplate the intrinsic nature of the mind, such a view arises, taking it to be the true self and holding that merely abiding in this principle is called liberation.
