維摩經玄疏 5.141

5.141

七、類通三種法身者：一，法身佛；二，報身佛；三，應身佛。真性解脫，即是法身，毘盧遮那佛，性淨法身；實慧解脫，即是報身，盧舍那佛，淨滿法身也；方便解脫，即是應身，釋迦牟尼佛，應化法身也。義推可解。

Seventh, analogously correlating the three kinds of dharma-body: first, the dharma-body Buddha; second, the reward-body Buddha; third, the response-body Buddha. The liberation of the true nature is the dharma-body, Vairocana Buddha, the naturally pure dharma-body; the liberation of real wisdom is the reward-body, Rocana Buddha, the pure and fulfilled dharma-body; the liberation of expedient means is the response-body, Śākyamuni Buddha, the responsive and transformed dharma-body. The meaning can be understood by inference.
