坐禪三昧經 2.71

2.71

行菩薩道者，於三毒中若愚癡偏多，當觀十二分，破二種癡：內破身癡，外破眾生癡。思惟念言：「我及眾生俱在厄難，常生、常老、常病、常死、常滅、常出，眾生可憐，不知出道，從何得脫？」一心思惟，生老病死從因緣生。當復思惟何因緣生？一心思惟，生因緣有、有因緣取、取因緣愛、愛因緣受、受因緣觸、觸因緣六入、六入因緣名色、名色因緣識、識因緣行、行因緣無明。如是復思惟，當何因緣滅生老死？一心思惟，生滅故老死滅、有滅故生滅、取滅故有滅、愛滅故取滅、受滅故愛滅、觸滅故受滅、六入滅故觸滅、名色滅故六入滅、識滅故名色滅、行滅故識滅、癡滅故行滅。

If among the three poisons ignorance is especially predominant in one who practices the bodhisattva path, they should contemplate the twelve links so as to destroy the two kinds of ignorance: destroying internal ignorance regarding the body, and destroying external ignorance regarding sentient beings. They reflect and think: 'I and all sentient beings are together in hardship and distress: constantly being born, constantly aging, constantly falling ill, constantly dying, constantly perishing, constantly emerging. Sentient beings are pitiful, not knowing the path of escape; from what can they attain liberation?' With one mind they contemplate: birth, aging, illness, and death arise from causes and conditions. They should then further contemplate: from what causes and conditions do they arise? With one mind they contemplate: birth is conditioned by becoming, becoming is conditioned by grasping, grasping is conditioned by craving, craving is conditioned by feeling, feeling is conditioned by contact, contact is conditioned by the six sense bases, the six sense bases are conditioned by name-and-form, name-and-form is conditioned by consciousness, consciousness is conditioned by formations, and formations are conditioned by ignorance. Thus they further contemplate: from the cessation of what causes and conditions will birth, aging, and death cease? With one mind they contemplate: because birth ceases, aging and death cease; because becoming ceases, birth ceases; because grasping ceases, becoming ceases; because craving ceases, grasping ceases; because feeling ceases, craving ceases; because contact ceases, feeling ceases; because the six sense bases cease, contact ceases; because name-and-form ceases, the six sense bases cease; because consciousness ceases, name-and-form ceases; because formations cease, consciousness ceases; because ignorance ceases, formations cease.
