妙法蓮華經玄贊 6.56

6.56

贊曰。下二頌半喻無色界災。初一頌半喻下三地惑，後一頌喻生有頂地惑。此初也。「蜈蚣」等類喻彼凡夫，為下色界惑火所燒，求生無色如走出穴生下三處。「鳩盤荼鬼」喻彼外道。外道多執二上地以為涅槃。撥諸凡夫不執以為殊勝涅槃，因凡起惑如鬼見虫隨取而食。食者資長義，隨逐彼生惑更增故。

The Commentary says: The two and a half verses below symbolize the calamities of the formless realm. The first one and a half verses symbolize the delusions of the lower three stages; the final one verse symbolizes the delusions born in the Peak of Existence stage. This is the first. Creatures such as "centipedes" symbolize ordinary beings who, being scorched by the fire of delusions in the lower form realm, seek birth in the formless realm, like rushing out of holes to be born in the lower three stages. "Kumbhāṇḍa demons" symbolize non-Buddhists. Non-Buddhists mostly grasp the two upper stages as nirvāṇa. They repudiate ordinary beings for not holding them to be superior nirvāṇa; giving rise to delusions on account of ordinary beings is like the demons seeing insects and seizing them to eat at will. "Eating" has the meaning of nourishing and growing, because pursuing those births makes delusions increase even more.
