無量壽經優婆提舍願生偈註 2.47

2.47

此云何不思議？夫寶例堅強而此柔軟，觸樂應著而此增道。事同愛作，何可思議？有菩薩字愛作，形容端正生人染著。經言「染之者，或生天上、或發菩提心。」

How is this inconceivable? Jewels are typically hard and rigid, yet these are soft; touching pleasure should induce attachment, yet this increases the path. In function it is identical to Love-Maker—how could it be conceivable? There is a bodhisattva named Love-Maker whose form is dignified, causing people to generate defiled attachment. A sūtra says: 'Those who feel attachment toward him either take birth in heaven or generate the bodhi-mind.'
