佛祖統紀 2.51

2.51

述曰。大乘開住胎。合降魔於成道。小乘開降魔。合住胎於託胎。住胎見起信。降魔見四教義。此先達之論也。今觀大小。皆有住胎降魔之文。如華嚴云。菩薩住母胎已。示現出家成道等相。此大乘住胎也。因果經。菩薩在母胎。行住坐臥。一日六時。為諸天鬼神說法。此小乘住胎也。花嚴離世間品。菩薩出家成道降魔轉法輪等。妙樂云。四佛各有四降魔相。此大乘降魔也。因果經。既降魔已即便入定。明星出時得最正覺。此小乘降魔也。今欲順八相之言。且用起信四教義二文開合為證。

The commentary states: Mahāyāna separates out 'dwelling in the womb' and merges 'subduing Māra' into 'attaining the Way.' Hīnayāna separates out 'subduing Māra' and merges 'dwelling in the womb' into 'entering the womb.' 'Dwelling in the womb' appears in the Awakening of Faith; 'subduing Māra' appears in the Sijiao yi. This is the argument of previous masters. Now, examining both the Mahāyāna and Hīnayāna, both contain texts on 'dwelling in the womb' and 'subduing Māra.' For instance, the Avataṃsaka states that after dwelling in the mother's womb, the Bodhisattva manifested the aspects of leaving home, attaining the Way, and so forth; this is the Mahāyāna 'dwelling in the womb.' The Guo qu xian zai yin guo jing says that while the Bodhisattva was in the mother's womb, during the six periods of the day, whether walking, standing, sitting, or lying down, he preached the Dharma to deities and spirits; this is the Hīnayāna 'dwelling in the womb.' The 'Leaving the World' chapter of the Avataṃsaka mentions the Bodhisattva leaving home, attaining the Way, subduing Māra, turning the wheel of the Dharma, and so forth; Miaole says that the four Buddhas each possess four aspects of subduing Māra; this is the Mahāyāna 'subduing Māra.' The Guo qu xian zai yin guo jing says that having subdued Māra, he immediately entered samādhi, and when the morning star appeared, he attained sambodhi; this is the Hīnayāna 'subduing Māra.' Now, wishing to conform to the formulation of the eight aspects, we temporarily use the division and merging found in the two texts of the Awakening of Faith and the Sijiao yi as evidence.
