 In addition to the emphasis on emptiness of all things as well as the Essence-Function paradigm, the Korean Buddhism also pledged allegiance to the doctrine of the womb (or embryo) of Buddhahood (tathāgatagarbha). This view holds that even deluded ordinary beings possess in their very make up the capacity to achieve enlightenment. The mind is intrinsically luminous but simultaneously dulled by adventitious defilements. Thus, the mind is not intrinsically ignorant but only contingently yet universally so. This capacity within the mind is called tathāgatagarbha (see, e.g., Suramgama Sutra).
