首楞嚴義疏注經 4.428

4.428

True awareness is like water; seeing and hearing are like turbidity; the body in samādhi is like a quiet vessel; the method of samādhi is like settling into quietude. Sand is like the afflictions; mud is like fundamental ignorance. Prior to the bhūmis is called 'subduing'; upon the bhūmis is called 'severing'; the ultimate is called 'pure and refined'; and manifestation is the arising of functioning. This is the same as the previous 'neither perishing nor arising tallying with the tathāgatagarbha', while the tathāgatagarbha is solely the wonderful awareness and illumination that completely illuminates the dharmadhātu, up to turning away from dust and tallying with awareness, and thus bringing forth the wonderful awareness and illuminated nature of tathatā.
