19.37

現形中，論　先是現形，如掬多令魔現佛形，八部翌從不覺禮拜等。若說下，是說法。陀羅尼，云遮持，謂持善遮惡故。然有多字、一字、無字，魔所說者應唯前二也，以不知唯心故，不能說無字。平等至無願，即三解脫門。無怨下，顯空義，可知。此魔但能說而不能證，天台云：魔能說別異空假中，不能證也。

Under "Manifesting bodily forms," the treatise first presents manifesting physical forms, such as Upagupta causing Māra to manifest the Buddha's physical form, so that the eightfold assembly accompanying him bowed down unconsciously, and so forth. From "If they speak" onward is preaching the Dharma. "Dhāraṇī" translates as "warding off and upholding," meaning upholding goodness and warding off evil. However, there are multisyllabic, single-syllable, and non-syllabic ones; those spoken by Māra should only be the former two, because not knowing mind-only, he cannot preach the non-syllabic. "Equanimity up to wishlessness" refers to the three gates of liberation. From "without enmity" onward reveals the meaning of emptiness, which can be understood. This māra can only speak of them but cannot realize them. Tiantai says: "Māra can speak of the distinct emptiness, conventionality, and the middle, but cannot realize them."
