大乘百法明門論開宗義決 1.118

1.118

謂若有法是帶已相心或相應等者。言有法者顯其緣義。無法非緣必不生心。要有體法方成緣故。帶已相者顯所緣義。要帶境相現於心上。令心得見成所緣故。心或相應是能帶體。心謂心王。相應心所。謂此有法所帶已相。乃是心王或善心所或惡心所所慮所託。

Regarding "If a dharma bears its own aspect, mind or mental factors associated with it": "a dharma" shows the meaning of being a condition (pratyaya); a non-existent dharma is not a condition and definitely does not produce mind; only a dharma with real essence can constitute a condition. "Bearing its own aspect" shows the meaning of being an object (ālambana); it must bear the aspect of an object and manifest it upon the mind, allowing the mind to perceive it and constitute an object. "Mind or associated" is the essence that bears: "mind" means the citta-rāja, and "associated" refers to mental factors. This means that its own aspect borne by this existing dharma is precisely what is contemplated and relied upon by the citta-rāja or wholesome mental factors or unwholesome mental factors.
