釋禪波羅蜜次第法門 10.17

10.17

所言初背捨者，不壞內外色，不內外滅色相已，是不淨心觀色，是名初背捨。所以者何？眾生有二分行：愛行、見行。愛多者，著樂，多縛在外結使；見多者，多著身見等諸見，為內結使縛。以是故，愛多者，觀外身不淨；見多者，觀內身不淨敗壞。今明背捨觀行，多先從內起，內觀既成，然後以不淨心觀外。

Regarding the first liberation: not having destroyed internal and external forms, and not having extinguished internal and external marks of form, one contemplates form with an impure mind; this is called the first liberation. Why is that? Sentient beings have two kinds of practice: craving-practice and view-practice. Those with excessive craving cling to pleasure and are mostly bound by external fetters; those with excessive views cling mostly to views such as the view of self and are bound by internal fetters. For this reason, those with excessive craving contemplate the impurity of external bodies; those with excessive views contemplate the impurity and decay of the internal body. Now, in clarifying the meditative practice of this liberation, it mostly begins first from the internal; once internal contemplation is accomplished, one then contemplates the external with an impure mind.
