다국어 초록 (Multilingual Abstract)

Gotama Siddhartha become a Buddha as he realized the law of depandant origination(緣起法). The thought of Banya·Gong is the thought revealing the original meaning of the law of depandant origination. The thought of Buddha nature has been developed from based on the thought of Banya·Gong.
『Yeolban-gyeong(涅槃經)』 dscourses that all the people certainly be enlightened based on ‘all the sentient beings have Buddha nature within(一 切衆生悉有佛性)’. There are In-Buddha nature(因佛性) and Gwa-Buddha nature(果佛性). In-Buddha nature is the cause for Buddha nature, therefore Gwa-Buddha nature is automatically appreared when people practice with in-Buddha nature.
The thought of Buddha nature has been elaborated in ‘the writing of Buddha nature in 『Yeolbanjongyo열반종요』’ by Bunhwang Wonhyo.
The following is that the first is the aspect of revealing the nature(本然) of Buddha nature, the second is the aspect of cause & effect of Buddha nature, the third is the aspect of seeing the nature of Buddha nature, the forth is the aspect of the existence & nonexistence of Buddha nature depending on the levels(階位), the fifth is the aspect of the past·present·future(三世) of Buddha nature, the sixth is the aspect of ‘the concilation of the diverse opinions(會通) of Buddha nature. Wonhyo discourses that one can achive enlightenment when the one is free from the both extremes which insists Buddha nature has ‘the true subtence(實體) defined Buddha nature’ by the ultimate true of empitness(第一義空), citing 「Sajahu-bosalpum(師子吼菩薩品)」. Further, during his discoursing about the aspect of the existence & nonexistence of Buddha nature, he explains the Buddha nature in the above position of the saint(聖人) citing 「Gaseob-bosalpum(迦葉菩薩品)」, and for the Buddha nature of ordinary people, he explains it by Sagu(四句) showing the middle path of Buddha nature(中道佛性) based on Euiji-mun and Yeongi-mun. The reason why explains Buddha nature in this way is one can get enlightenment(成佛) after being free from the attachment of the both extrems of the existence & nonexistence of Buddha nature
