楞伽阿跋多羅寶經註解 1.597

1.597

答言非諸外道因緣等者，蓋外道修證非正因緣，因非正因、果非正果，故徵釋而斥之。不因自相成者，謂非自覺相所成，則常不思議境界之果亦不成也。彼因若從自覺相成，則因常而果亦常也。言由作因相等者，由所作之因是邪計故，所以常不思議不成果也。

The answer stating 'It is not through the causes and conditions of all the tīrthikas' and so forth is because the cultivation and realization of tīrthikas are not proper causes and conditions: their causes are not proper causes, and their fruits are not proper fruits; therefore it queries, explains, and refutes them. 'Not accomplished through svalakṣaṇa' means that it is not accomplished through the marks of self-realization, and thus the fruit of the realm of the eternal and inconceivable is also not accomplished. If their cause were accomplished from the marks of self-realization, then because the cause is eternal, the fruit would also be eternal. Saying 'Because of the causal mark of a creator' and so forth means that because the cause produced is a perverse grasping, the eternal and inconceivable does not become an accomplished fruit.
