妙法蓮華經玄義 5.6

5.6

名義俱圓者，文云：「開示悟入，皆是佛之知見。」佛一切種智知、佛眼見，此之知見，無有缺減。又，入如來室，坐如來座，以如來莊嚴，此則名義俱圓，判於圓位也。

Regarding 'both the name and the meaning are perfect,' the text states: 'Opening, demonstrating, awakening, and entering are all the insight and vision of the Buddha.' Known by the Buddha's knowledge of all aspects and seen by the Buddha eye, this insight and vision is without deficiency or decrease. Furthermore, entering the Tathāgata's room, sitting on the Tathāgata's seat, and adorned with the Tathāgata's adornments—this means both name and meaning are perfect, classified as the perfect stages.
