大乘百法明門論疏 1.7

1.7

解云：「此初第一、引經標宗，明法無我。如佛世尊諸經，皆說一切法中都無有我。故今舉教標以為宗。」

The commentary states: "This is the first: citing the sūtra to indicate the central thesis, clarifying the selflessness of dharmas (dharma-nairātmya). As the various sūtras of the Buddha, the World-Honoured One, all state that among all dharmas there is absolutely no self, he now cites the teaching to indicate it as the central thesis."
