楞伽阿跋多羅寶經註解 3.5

3.5

三種意生身，乃通教菩薩自行化他之道，為菩薩者不可不知，故如來不待問而告之。初列三名，而後徵釋。

The three kinds of mind-made bodies are the path of self-cultivation and transforming others for bodhisattvas of the Shared Teaching; one who is a bodhisattva cannot fail to know them, and therefore the Tathāgata informs him without waiting to be asked. First, the three names are listed, and then they are examined and explained.
