首楞嚴義疏注經 2.316

2.316

自住之定即首楞嚴三昧也。諸法如幻，法界一相，《起信》云「諸佛已離業識，無自他相見。登地已上分證此法，亦如佛見也。」

The concentration in which they themselves abide is the Śūraṅgama samādhi. All dharmas are like illusions, and the dharmadhātu has a single characteristic. The *Awakening of Faith* states: "All Buddhas have already left behind the karmic consciousness and have no characteristic of self and other seeing each other. Those who have ascended to the grounds and above partially realize this dharma, seeing just as the Buddhas see."
