首楞嚴義疏注經 4.18

4.18

「而我不知是義攸往，惟願如來宣流大慈，開我迷雲及諸大眾。」作是語已，五體投地，欽渴如來無上慈誨。

"Yet I do not know where this meaning leads. I only wish that the Tathāgata will pour forth his great compassion to clear away the clouds of delusion for me and for the great assembly." Having spoken these words, he cast the five limbs of his body to the ground, thirsty with veneration for the Tathāgata's unsurpassed, compassionate instruction.
