妙法蓮華經玄義 6.204

6.204

若修持十善，任運無間，善心成熟即天業。故云：純惡心無善念間者，即惡道業，果時純苦故。善惡相間起即人業，人中果報苦樂相間故。十善任運成是天業，天中果報自然故。若修十善兼起護法心，即四天王業。若修十善兼慈化人，是三十三天業。若修十善，其心細妙任運成熟，行住坐臥不惱眾生，善巧純續，是焰摩業。若修十善兼修禪定攝心，麁住細住者，是兜率業；欲界定是化樂業；未到定破事障，是他化業；四禪是色界業；兼於慈悲喜捨，心數法中得定，是梵王業；滅心修無心定，是無想業。

If one cultivates and maintains the ten wholesome actions naturally and without interruption, and the wholesome mind matures, this is celestial karma. Therefore it is said: A mind of pure evil, uninterrupted by wholesome thoughts, is the karma of the evil destinies, because the fruit is pure suffering. Wholesome and unwholesome arising in alternation is human karma, because the fruit in the human realm alternates between suffering and pleasure. The ten wholesome actions naturally fulfilled are celestial karma, because the retribution in the heavens is spontaneous. If one cultivates the ten wholesome actions and concurrently gives rise to the mind of protecting the Dharma, that is the karma of the Four Heavenly Kings. If one cultivates the ten wholesome actions and concurrently transforms people with loving-kindness, that is the karma of the Thirty-Three Gods. If one cultivates the ten wholesome actions, and one's mind is subtle, exquisite, naturally matured, not vexing sentient beings in walking, standing, sitting, or lying down, being purely continuous with skillful means, that is the karma of the Yāma [heavens]. If one cultivates the ten wholesome actions and concurrently cultivates dhyāna concentration to collect the mind, reaching coarse abiding and subtle abiding, that is the karma of the Tuṣita [heavens]; the concentration of the desire realm is the karma of the Nirmāṇarati [heavens]; the threshold concentration that shatters phenomenal hindrances is the karma of the Paranirmitavaśavartin [heavens]; the four dhyānas are the karma of the form realm; concurrently attaining concentration within the mental factors of benevolence, compassion, sympathetic joy, and equanimity is the karma of the Brahmā Kings; and extinguishing the mind to cultivate the concentration of non-conception is the karma of the realm of non-conception.
