大毘盧遮那成佛經疏 11.6

11.6

「於長恒時殊勝進，隨念施與無上果」者，恒謂常修如是法行，乃至大空亦不可得，無自性故。猶如大空而能生起萬行，此甚深平等法界之行，行者若能常如是行，即能隨眾生所思願而滿足之，乃至無上大願亦能與彼也。

Regarding "Advancing with special excellence through long and enduring time, / it bestows the unexcelled fruit in accordance with one's thoughts": enduring means constantly cultivating such Dharma practices, up to even great emptiness being unattainable because it has no intrinsic nature. Just as great emptiness can give rise to the myriad practices, so it is with this practice of the profound, equal dharmadhātu: if a practitioner can constantly practice like this, they can fulfill what sentient beings desire and wish for, and can even bestow upon them the unexcelled great vow.
