楞伽阿跋多羅寶經註解 1.668

1.668

此因建立。言初識無因生者，謂最初識念無因而生，生後不實如幻。既然如幻，豈有生乎？眼、色、明、界等者，言初識本無，後因眼等四緣一念前生，生已實有，實已還壞，是為生滅，故皆非也。

This is the affirmation of causes. To say 'the initial consciousness arises without a cause' means that the very first thought of consciousness arises without a cause, and after arising it is unreal like an illusion. Since it is like an illusion, how could there be production? 'The eye, form, light, realm, etc.' means that the initial consciousness is fundamentally nonexistent, and later, due to the four conditions such as the eye, a thought arises before; having arisen, it is real, and having become real, it decays again; this is production and cessation, and therefore all are incorrect.
