大方廣佛華嚴經疏 33.13

33.13

二釋名者，此論所釋已見本分，當經有釋備於下文，今引他部成立正義。《唯識》第九云「初獲聖性具證二空，能益自他，生大喜故。此有三義：一得位、二證理、三成行。由此三故，名極歡喜。」《攝大乘論》第七云「由此最初得能成辦自他義利勝功德故。」此唯依第三成行義說。《十住毘婆沙》云「始得法味生大歡喜故。」此唯約證理義說。《瑜伽》七十八引《深密經》云「成就大義，得未曾有出世間心，生大歡喜故。」此約二義，大義即是二利行成出世間心是得聖位，此同本論本分中釋。

Second, regarding the explanation of the name: the explanation in this treatise has already appeared in the fundamental section, and the present sūtra's own explanation is fully provided in the text below. Here we cite other works to establish the correct meaning. Fascicle nine of the Vijñaptimātratāsiddhi states: 'First obtaining the noble nature and fully realizing the two emptinesses, one can benefit oneself and others, giving rise to great joy. This contains three meanings: first, attaining the station; second, realizing the noumenon; third, accomplishing the practice. By virtue of these three, it is named "Utmost Joy" (pramuditā).' The seventh fascicle of the Mahāyānasaṃgraha states: 'Because here one first attains the superior virtue capable of accomplishing the benefit and welfare of self and others.' This speaks solely on the basis of the third meaning, the accomplishment of practice. The Daśabhūmika-vibhāṣā states: 'Because one initially attains the taste of Dharma, great joy arises.' This speaks solely with reference to the meaning of realizing the noumenon. Fascicle seventy-eight of the Yogācārabhūmi, citing the Saṃdhinirmocana-sūtra, states: 'Because one accomplishes great benefit and attains an unprecedented supramundane mind, great joy arises.' This relies on two meanings: the great benefit is the accomplishment of the practice of dual benefit, and the supramundane mind is the attainment of the noble station. This accords with the explanation in the fundamental section of the treatise itself.
