《徐霞客游记·粤西游日记三十六》
由观音菩萨佛完后举着火把进去，洞口不怎么宽大；渐渐进去逐渐变高变宽，有石柱石门；转过几个弯，又逐渐变窄；脚下的石头开始崎岖不平，不再是平坦的洞底了。
由大士龛后秉炬入，门颇不宏；渐入渐崇拓，有石柱石门；宛转数曲，复渐狭；其下石始崎嵚，非复平底矣。
After the Goddess of Mercy, the Buddha held a torch and went in, the entrance of the cave was not very wide; gradually going in it becomes higher and wider, there are stone pillars and stone gates; after making a few turns, it gradually gets narrower; the stones underfoot begin to be rough and uneven, it is no longer the flat bottom of the cave.
