維摩經玄疏 5.47

5.47

五、明觀心即是經者，經由觀心，得成聖也。故《般舟經》云：「諸佛從心得解脫，心者無垢名清淨，五道鮮潔不受色，有解此者成大道。」

Fifth, clarifying that contemplating the mind is itself the sūtra: By passing through contemplating the mind, one succeeds in becoming a sage. Therefore, the Banzhou Jing says: 'All Buddhas attain liberation from the mind; the mind is free of defilement and called pure; the five destinies are immaculate and do not grasp form; one who understands this accomplishes the Great Path.'
