 So, what is the nature of the ultimate reality of the world? Chinul typically calls the unconditioned reality of the world “True Mind (chinsim 眞心)”. This is the same as Buddha-nature. “True” here means the absolute lack of any illusion, or in his words, “to leave behind the false”. “Mind” means the source of reality that is the numinous mirror. In particular, it is not used as the mental faculty of an individual human being. As such, the True Mind is not properly describable. It can only be symbolized. For example, it is symbolized by dharmadhātu in the Avataṃsaka Sūtra. Following the Sutra, Chinul holds that the phenomena of the world are formed because of the works of the mind. There is no separate world outside the mind. Chinul thus speaks of mind sive Buddha. The mind makes the Buddhas.
