中觀論疏 7.21

7.21

長行前釋上半，為破二事是故說空：一破諸見、二破諸愛，此愛見通內外大小。「若人於空」下，釋下半，又開四別：初法說；「譬如」下，第二譬說；「如空」下，第三合譬；「若離是空」下，明佛教用空之意也。

The prose commentary first explains the first half of the verse: emptiness was taught in order to eliminate two things: first, to eliminate all views; second, to eliminate all cravings. These cravings and views pervade both internal and external [teachings], both Mahāyāna and Hīnayāna. From "If a person with respect to emptiness" downward explains the second half, again opening into four distinct parts: first, the exposition of the principle; from "Just as" downward is the second, an exposition by simile; from "Like emptiness" downward is the third, applying the simile; from "If one departs from this emptiness" downward clarifies the intent of the Buddha's teaching in utilizing emptiness.
