7.191

一切法空者。此是義宗。若是上根聞之便解，中根之類一喻即明，下根之流展轉生惑。更以諸喻如下所辨。

"All phenomena are empty": this is the fundamental doctrine. If one is of superior capacity, upon hearing it one immediately understands; those of middling capacity understand upon a single analogy; while the stream of inferior capacity generates further delusion progressively. Hence, further analogies are used as distinguished below.
