13.26

染淨相資。資，取也，即藉賴之義，謂染法淨法自不能生，以互相取，假其勢力，以為藉賴之緣，方得生故。又資者，助益義，謂互相資助令生染淨故。以前科但明染淨當位生滅之義，而未廣明染法淨法生起行相。今即說之，意明染淨互相資假、互相助益，生一切法。如染助於淨、淨假於染，則淨法隨流生諸染法；淨助於染、染假於淨，則染法反流生諸淨法。本雖相違，反成相順，染法淨法遞互相假也。

Defilement and purity mutually support each other. "Support" (zi) means to draw upon, which is the meaning of relying on and depending upon. This means that defiled dharmas and pure dharmas cannot arise on their own; because they mutually draw upon each other and borrow each other's momentum as the conditions of reliance, they are able to arise. Furthermore, "support" has the meaning of aiding and benefiting; it means that they mutually assist and benefit each other to cause the arising of defilement and purity. Because the preceding section only explained the meaning of the arising and ceasing of defilement and purity in their proper positions, but had not yet broadly explained the active aspects of the arising of defiled dharmas and pure dharmas. Now this is explained: the intention is to clarify that defilement and purity mutually support and borrow from each other, mutually assist and benefit each other, and produce all dharmas. As defilement assists purity and purity borrows from defilement, pure dharmas follow the flow [of samsara] and give rise to various defiled dharmas; as purity assists defilement and defilement borrows from purity, defiled dharmas reverse the flow and give rise to various pure dharmas. Though originally contrary to each other, they turn out to be mutually compliant: defiled dharmas and pure dharmas alternately borrow from each other.
