四、辨三法不立食，補闕云：眠夢等法，於報根大無損害故，名長養。然不能攝受別生長養根大分，故不名食。天眼雖從等至所發，乃是定中觸思食生，故食能生，長養根大，非食不能也。

Fourth, distinguishing why three dharmas are not established as nutriment. The supplement says: dharmas such as sleep and dreams do not cause damage to the faculties and great elements of karmic fruition, hence they are called nourishing. However, they cannot embrace and separately generate a distinct portion that nourishes the faculties and great elements, hence they are not called nutriment. Although the divine eye is generated from meditative attainment, it is generated by the nutriments of contact and mental volition within concentration; hence nutriment can generate and nourish the faculties and great elements, whereas non-nutriment cannot.
