摩訶止觀 1.63

1.63

又九種是生死，如蠶自縛；後一是涅槃，如麞獨跳，雖得自脫，未具佛法，俱非故雙簡。前九是世間，不動不出；後一雖出，無大悲，俱非，雙簡也。有為無為、有漏無漏、善惡、染淨、縛脫、真俗等種種法門亦如是。

Furthermore, the [first] nine kinds are birth-and-death, like a silkworm binding itself; the last one is nirvāṇa, like a roe deer leaping alone—though it achieves self-escape, it has not yet completed the Buddha-dharma; because both are incorrect, both are eliminated. The former nine are worldly, neither moving nor escaping; although the last one escapes, it lacks great compassion; since both are incorrect, both are eliminated. The various Dharma gateways of conditioned and unconditioned, with outflows and outflow-free, good and evil, defiled and pure, bound and liberated, true and conventional, are also like this.
