妙法蓮華經玄贊 6.329

6.329

贊曰：二人依教也。以教扣機如求窮子，以法稱器令彼聞知，故言得之。述斷煩惱，名陳上事。

Commentary: The two men acting according to instructions. Reaching his capacity through teaching is like searching for the impoverished son; matching his vessel through the Dharma and causing him to hear and understand is why it says 'found him.' Explaining the severing of defilements is called 'setting forth the matter above.'
