摩訶止觀 8.189

8.189

治魔羅有三：一、初覺呵，如守門人遮惡不進。如佛告比丘：「一切他物不受。」不受之術能治一切自他魔事。二、若已受入，當從頭至足一一諦觀，求魔叵得，又求心叵得。魔從何來？欲惱何等？如惡人入舍，處處照檢，不令得住。三、觀若不去，強心抵捍，以死為期，不共爾住。善巧迴轉如是三治，不須多說。

Remedying māra has three [methods]: First, becoming aware at the outset and scolding it, like a gatekeeper blocking evil from entering. As the Buddha told the monks: 'Do not accept any external objects.' The method of non-acceptance can remedy all māra affairs of self and other. Second, if it has already been received and entered, one should contemplate closely from head to foot, seeking māra without finding it, and seeking the mind without finding it: 'From where did māra come? What does it wish to disturb?' Like an evil person entering a house, one illuminates and inspects everywhere, not letting him remain. Third, if through contemplation it does not leave, strengthen the mind to resist it, taking death as the limit: 'I will not abide together with you.' Skillfully revolving these three remedies—there is no need to speak further.
