華嚴經旨歸 1.30

1.30

問：「若此多劫常恒說者，何故如來有涅槃耶？」答：「說此經佛本不涅槃，〈法界品〉中開旃檀塔，見三世佛無涅槃者。又復以此初時既攝多劫，是故示現涅槃亦在此中，以攝化威儀之中涅槃，亦是說法攝生與成道說法無差別故，是故說法總無休時。復次，舍那佛常在華藏，恒時說法，初無涅槃如常住故。」

Question: "If it is constantly and eternally expounded over these many kalpas, why does the Tathāgata enter nirvāṇa?" Answer: "The Buddha who expounds this sūtra fundamentally does not enter nirvāṇa; in the 'Chapter on the Dharmadhātu', the sandalwood pagoda is opened and one sees that none of the Buddhas of the three periods of time enter nirvāṇa. Furthermore, because this initial time already encompasses many kalpas, the manifestation of entering nirvāṇa is also within this, because nirvāṇa within the deportments of gathering and transforming [beings] is also expounding the Dharma and gathering sentient beings, not different from attaining enlightenment and expounding the Dharma; therefore, the expounding of Dharma has no time of cessation at all. Furthermore, Rocana Buddha is constantly in Padmagarbha, eternally expounding the Dharma, never entering nirvāṇa, as he is eternally abiding."
