觀心論疏 2.14

2.14

次答上第三問「云何約自生一句起三十六問」者，經云「不內觀得是智慧，乃至非內外觀得是智慧，亦不離內外觀得是智慧。」今亦爾，四句求生不可得，亦不離自他四句。論主又明不生則不有、不滅即不無，不無故得約自生一句起三十六問也。餘他生、共生、無因生亦然也。

Next, to answer the third question above, 'How does one raise thirty-six questions with reference to the single phrase "self-arising"?': The sūtra says, 'Not contemplating internally does one attain this wisdom, up to not contemplating internally and externally does one attain this wisdom, nor apart from contemplating internally and externally does one attain this wisdom.' Now it is also like this: seeking arising through the four tetralemmas is impossible, yet it is also not apart from the four tetralemmas of self and other. The author of the treatise also clarifies that not arising means not being existent, and not ceasing means not being non-existent; because it is not non-existent, one can raise thirty-six questions with reference to the single phrase 'self-arising'. The rest—other-arising, arising from both, and causeless arising—are also like this.
