大般涅槃經義記 3.291

3.291

就初段中，「王」喻如來，三千世界佛所化處名為「王家」，凡夫眾生惑性增強名為「力士」，心有佛性故言「眉間有金剛珠」，諸惡知識名「餘力士」，由近惡友，彼此煩惱同皆現起，故云「捔力」，相領善法名為「相撲」，心對惑緣名「頭抵觸」，心中之性為相隱覆名「額上珠尋沒膚中」，隱而不覺名「不自知是珠所在」，由性隱覆多受諸苦名「處有瘡」。

Within the first section, the “king” is a metaphor for the Tathāgata; the trichiliocosm, the place transformed by the Buddha, is called the “king's household”; ordinary sentient beings whose deluded nature has grown strong are called “wrestlers”; having the buddha-nature in the mind is why it says “having a diamond jewel between his eyebrows”; bad spiritual associates are called the “other wrestlers”; due to nearing bad friends, the afflictions of both manifest together, hence it says “contending in strength”; mutually contending over good dharmas is called “wrestling”; the mind confronting conditions for delusion is called “butting heads”; the nature in the mind being veiled by characteristics is called “the jewel on his forehead thereupon sank into his flesh”; being veiled and unaware is called “not knowing for himself where the jewel was”; due to the nature being veiled, undergoing much suffering is called “there was a sore on the spot.”
