首楞嚴義疏注經 3.270

3.270

「是故當知，身觸為緣生身識界，三處都無，則身與觸及身界三，本非因緣、非自然性。」

"Therefore, you should know that the body and tangibles, acting as conditions, generate the body-consciousness element. The three loci are completely non-existent; hence body, touch, and the body element—these three—are fundamentally neither conditioned co-arising nor nature of spontaneity."
