注大乘入楞伽經 8.83

8.83

此復破轉計也。若言如來如虛空常者，則不待自覺智所修因成，以虛空離四句邊分，得譬如來也。又若言如來是不生常者，則如兔馬等角，本來無生也。若同虛空兔馬言常，則無方便廣大益物義，是故不同也。

This further refutes a subsequent misconception. If one says that the Tathāgata is permanent like space, then he would not depend on the causes cultivated by self-realized knowledge to be accomplished, for space, being free from the extremities of the four tetralemmas, can be used as a metaphor for the Tathāgata. Moreover, if one says that the Tathāgata is permanent because he is unarisen, then he would be like the horns of a hare or horse, which are originally unarisen. If one asserts permanence by equating him with space or the horns of a hare or horse, then there would be no meaning of great expedient means benefiting sentient beings; therefore, he is not the same.
