妙法蓮華經玄贊 9.556

9.556

贊曰：結成歡喜。諸具善根者聞佛名故，助佛無上心、修行順佛心。或令彼具善根，助彼眾生生無上心，名為助也。

The Eulogy says: Concluding the rejoicing. Because those possessing roots of goodness heard the Buddha's name, they aided the Buddha's unsurpassed mind, practicing in accordance with the Buddha's mind. Alternatively, it means causing them to possess roots of goodness and aiding those sentient beings to generate the unsurpassed mind; hence it is called 'aiding'.
