觀音義疏 2.50

2.50

If responding from wondrous awakening to the realm of true reward, he possesses complete marks and signs, with immeasurable light; identical with the sentient beings of the realm of true reward across the forty-one stages, he preaches for them the genuine Dharma of the one real truth to teach and transform them. Such a response is not something that the other realms can sustain. Why is this? Those in these various stages have already partially entered the stages, so one cannot respond to them with a body of other realms, nor may one respond to them with another Buddha body; such a response responds only to that land, and cannot be sustained by other lands.
