仁王般若經疏 1.61

1.61

問：何故諸天有不聞法者、三途而來受道？答：天台智者言：於此《涅槃經》於戒緩者不名為緩，於乘緩者乃名為緩。於此作四句分別，自有乘急而戒緩、戒急而乘緩、俱急、俱緩。以其過去持戒修定故生天，以其過去不修慧故不得聞經。三途而來受道者，以其破戒墮三途，以其過去世修慧，故為聲光所招。俱急、俱緩可知。

Question: Why were there devas who did not hear the Dharma, while [beings of] the three miserable paths came to receive the Path? Answer: Tiantai Zhizhe said: In this Mahāparinirvāṇa-sūtra, being lax in precepts is not called lax; being lax in the Vehicle is called lax. In this regard, a fourfold distinction is made: there are those eager in the Vehicle but lax in precepts; eager in precepts but lax in the Vehicle; eager in both; and lax in both. Because in the past they kept precepts and cultivated absorption, they were born in heaven; because in the past they did not cultivate wisdom, they were unable to hear the sūtra. Those who came from the three miserable paths to receive the Path: because they broke precepts they fell into the three miserable paths, but because in past lives they cultivated wisdom, they were summoned by the sound and the light. Being eager in both or lax in both can be understood [from this].
