『圓覺經』의 圓覺妙心과 頓悟漸修論에 관한 연구 -圭峯宗密의 해석을 중심으로-

Abstract

Marvelous Mind of Perfect Enlightenment (圓覺妙心) that is the key thought of Sutra of Perfect Enlightenment (Yuanjue jing) preaches the theory of practice in order to achieve the character of perfect enlightenment. The character of perfect enlightenment (圓覺性) is inherently endowed with all sentient beings even though the variation of several terminologies are found throughout the whole sutra,Regarding the discussing about the thought of perfect enlightenment, we should not oversight the Tathāgata-garbha thought that is the fundamental thought of the perfect enlightenment. Accordingly, I would like to review the sutras related to the Tathāgata-garbha thought first and then their relatedness with the thought of perfect enlightenment. Also I would like to examine how the fundamental thought, ‘perfect enlightenment’ discussed in the each chapter of the Sutra of Perfect Enlightenment is explained. And on the basis of the sudden enlightenment of “perfect enlightenment is inherent (本有 original existence) and ignorance is non-existent (本無 original nonexistence)” that taught by the virtuous teacher, I would like to examine how to eradicate the karmic impressions (習氣) of many lives in terms of sudden enlightenment and gradual practice. I would like to write this paper with a focus on the Master Guifeng's annotations of Sutra of Perfect Enlightenment.
