6.129

釋釋初門中，有種子法。由現有故等者，景云：由無姓來於所依中，念念現成聲聞種姓，無漏種子遇緣即生，見道無漏漸入涅槃。

Regarding the explanation of the first gate, "there are dharmas of seed-nature; because they are presently existing," and so forth: Jing says that since beginningless time, within the locus of reliance, the śrāvaka gotra is presently accomplished moment by moment; when untainted seeds encounter conditions, they directly arise, and through the untainted [path] of seeing, one gradually enters nirvāṇa.
