金光明最勝王經疏 2.333

2.333

贊曰：出三身體，即分三段。此化身體，初假為問、二佛為答、三者雙結。此即初也。言菩薩者，對所備機。定性二乘不能忻求，故問菩薩。雖三乘俱得名菩薩，然非皆問意。問大乘菩薩云何了知，欲令忻樂修行求故。即是二問：一云何菩薩？二云何了知？

The commentary says: Defining the essential nature of the three bodies is divided into three sections. Regarding the essential nature of this transformation body: first, setting up the question; second, the Buddha gives the answer; third, concluding both. This is the first part. In speaking of 'bodhisattva', it addresses the ready capacity. The two vehicles of determined nature cannot aspire to and seek this, so he asks about the bodhisattva. Although all three vehicles can be called bodhisattvas, that is not the intention of the question. He asks how Mahāyāna bodhisattvas fully understand it, wishing to cause them to aspire to, cultivate, and seek it with joy. That is, there are two questions: first, how is it a bodhisattva? Second, how is it fully understood?
