56.1

辨因果非有非無義　廣辨正因緣因義　廣辨了因緣因義　師子吼更設七翻難責無佛性　第一謂人無性人可作天天可作人義故知無性　第二論闡提斷善根故知無佛性　第三有初發心故知無佛性　第四退故知無佛性　第五證萬善是性離善則無性　第六因有強弱故知無性　第七以菩提心本無今有故知無佛性　下廣答七難　廣辨退不退性　辨修三十二相等

Discerning that cause and effect are neither existent nor non-existent; extensively discerning the meanings of direct cause and contributory cause; extensively discerning the meanings of revealing cause and contributory cause; Siṃhanāda further presents seven rounds of objections challenging the non-existence of buddhadhātu; first, stating that since humans have no fixed nature, a human can become a deva and a deva can become a human, one thus knows there is no [fixed] nature; second, arguing that because icchantikas sever their roots of goodness (kuśalamūla), one thus knows there is no buddhadhātu; third, that because there is an initial arousal of the aspiration, one thus knows there is no buddhadhātu; fourth, that because of retrogression, one thus knows there is no buddhadhātu; fifth, proving that the myriad good qualities are the nature, and apart from the good there is no nature; sixth, that because causes have strength and weakness, one thus knows there is no nature; seventh, that because the bodhicitta was originally absent and is now present, one thus knows there is no buddhadhātu; below, extensively answering the seven objections; extensively discerning the nature of retrogression and non-retrogression; discerning the cultivation of the thirty-two marks, etc.
