摩訶止觀 4.41

4.41

Moreover, one knows that upholding the "phenomenal precepts" has three grades: the upper grade attains retribution in the heavens, the middle grade attains retribution as humans, and the lower grade attains retribution as asuras. Transgressing the upper falls from the heavens, transgressing the middle falls from humans, and transgressing the lower falls from asuras, entering the three evil destinies. The evil destinies also have three grades: the light enters the hungry ghost destiny, the middling enters the animal destiny, and the heavy enters the hell destiny. The middle grade also has many kinds: upper, middle, lower, and lowest of the low, which are the four continents. The upper grade also has many kinds: that is, the various heavens of the three realms, each having its rank.
