大乘起信論義記 3.455

3.455

[The demon] may manifest the form of a deva or a bodhisattva, or also take the form of a Tathāgata endowed with the major and minor marks. Or it may speak dhāraṇīs, or preach giving, morality, forbearance, diligence, dhyāna, and wisdom; or preach equality, emptiness, signlessness, wishlessness, freedom from enmity and friendship, freedom from cause and effect, [teaching that] ultimate emptiness and tranquility are true nirvāṇa. Or it may cause a person to know events of past lifetimes and know future events as well, obtaining knowledge of other minds and unhindered eloquence, and can cause sentient beings to greedily cling to worldly fame and profit. It also causes a person to frequently become angry and frequently become joyful, having a temperament without constancy. Or they may have much affection, much sleep, or much illness, with their mind being indolent. Or they may abruptly arouse diligence but later abandon it, giving rise to lack of faith with much doubt and anxiety. Or they may abandon their original superior practice and instead cultivate miscellaneous activities, or cling to worldly affairs with various entanglements. It can also cause a person to attain a slight resemblance to various samādhis, which are all attained by non-Buddhists and are not true samādhi. Or it may cause a person to remain in meditative absorption for one day, two days, three days, or even up to seven days, obtaining naturally fragrant and delicious food and drink so that body and mind are comfortable, free from hunger and thirst, causing the person to become attached. Or it may cause a person to have no measure in eating, eating suddenly much and suddenly little, with changes in facial complexion.
