心性

Immutable mind-corpus, or mind-nature, the self-existing fundamental pure mind, the all, the Tathāgata-garbha, or [lang id =1028]如來藏心; [lang id =1028]自性清淨心; also described in the [lang id =1028]起信論 <Awakening of Faith> as immortal [lang id =1028]不生不滅. Another definition identifies [lang id =1028]心 with [lang id =1028]性 saying [lang id =1028]性卽是心, [lang id =1028]心卽是佛 the nature is the mind, and mind is Buddha; another, that mind and nature are the same when [lang id =1028]悟 awake and understanding, but differ when [lang id =1028]迷 in illusion; and further, in reply to the statement that the Buddha-nature is eternal but the mind not eternal, it is said, the nature is like water, the mind like ice, illusion turns nature to mental ice form, awakening melts it back to its proper nature.
