梵網經古迹記 2.33

2.33

述曰：自下佛序，如次序成師、法、弟子三輪相也。師有二種：一、本謂佛，二、末菩薩。故言我誦，汝等亦誦。「半月誦」者，雖師隱沒，依法住故。增即易退，減即難進。為不退戒，進修定慧，是故半月不增不減。如《遺教》云：「波羅提木叉是汝等師，若我住世，無異此也。」言「發心」者，十信位也。行實有退，非三賢之正位。「十發趣」者，十住也，三賢初故。「十長養」者，十行也，長養聖胎故。「十金剛」者，十迴向也，攝五力故。本業下卷，皆地前故。戒能破暗，以光為瑞。常所誦持，從口而出，故說「有緣非無因」也。

The Commentary says: Below is the Buddha's preface, setting forth in turn the characteristics of the three wheels of teacher, Dharma, and disciple. There are two kinds of teachers: first, the fundamental teacher, meaning the Buddha; second, the derivative, the bodhisattvas. Hence it says 'I recite, and you should also recite.' 'Recite every half-month': although the teacher has disappeared, they abide relying on the Dharma. Adding leads easily to regression, and subtracting makes advancement difficult. To avoid regressing from the precepts and to advance in cultivating concentration and wisdom, every half-month neither adds nor subtracts. As the Legacy Teaching says: 'The prātimokṣa is your teacher; if I remained in the world, it would be no different from this.' 'Generating the aspiration' refers to the stage of the ten faiths. The practice still has regression, so it is not an official stage of the three classes of worthies. 'Ten launchings' are the ten abodes, being the first of the three classes of worthies. 'Ten nourishings' are the ten practices, because they nourish the sacred embryo. 'Ten vajras' are the ten dedications, because they gather the five powers. In the lower fascicle of the Benye [jing], all are prior to the grounds (bhūmis). Precepts can destroy darkness, using light as an auspicious sign. What is constantly recited and held emerges from the mouth, so it says 'it has conditions and is not without cause.'
