摩訶止觀 9.54

9.54

若壞法人修九想：一、脹想，二、壞想，三、血塗想，四、膿爛想，五、青瘀想，六、噉想，七、散想，八、骨想，九、燒想。此人但求斷苦，燒滅骨人，急取無學，不欣事觀。既無骨人可觀，便無禪定、神通變化、願智頂禪。雖言燒滅，實有身在，例如滅受想而身證（云云）。此人好退，如《毘曇》有退相，四果如沙住井底。《阿含》云：「三果退戒還家，毀失律儀，不失道共。俗人生謗，言無聖法。佛言：『欲飽起厭，不久當還，更求出家。』諸比丘不度，佛即度之，便得羅漢。阿難問言：『大德，是學退、無學退？』答言：『學退。』」若然，即是世智斷惑慧解脫人，故得有退；非無漏智斷一品惑、進一品解，而有退也。若發此九想，無諸禪功德者，是壞法人也。

If a person of destructive disposition cultivates the nine contemplations: first, the contemplation of bloating; second, the contemplation of rupturing; third, the contemplation of bloody smear; fourth, the contemplation of purulent decomposition; fifth, the contemplation of blue-bruising; sixth, the contemplation of devouring; seventh, the contemplation of scattering; eighth, the contemplation of the skeleton; ninth, the contemplation of burning. This person seeks only to sever suffering, burns and extinguishes the skeleton, hastily grasps the stage of the non-learner, and takes no joy in phenomenal contemplation. Since there is no longer a skeleton to contemplate, there are no meditative absorptions, supernormal powers and transformations, or the summit dhyāna of knowledge born of aspiration. Although called "burned and extinguished," there is actually a body present, just as with physical realization of the cessation of perception and feeling (and so forth). Such a person is prone to falling back; as in the Abhidharma, there are characteristics of falling back, where the four fruits are like sand dwelling at the bottom of a well. The Āgamas state: "One of the third fruit fell back in morality and returned home, ruining and abandoning the disciplinary rules, yet without losing the morality associated with the path. Worldly people gave rise to slander, saying there is no noble Dharma. The Buddha said: 'When his desires are satiated, aversion will arise; before long he will return and seek to leave the household again.' The monks would not ordain him, so the Buddha himself ordained him, whereupon he attained arhatship. Ānanda asked: 'O Venerable One, was this a falling back of a learner or of a non-learner?' The Buddha replied: 'A falling back of a learner.'" If so, this is a person liberated through wisdom who severs defilements by worldly knowledge, and therefore can fall back; it is not that one severs a grade of defilement and advances a grade of understanding through uncontaminated wisdom and yet falls back. If one develops these nine contemplations without having the virtues of the dhyānas, one is a person of destructive disposition.
