法華義疏 4.155

4.155

具三身也。初、明居法身之地見物有苦無樂起大悲心。次、初成道時為諸菩薩說華嚴教，則盧舍那身。第三門、為諸聲聞說三乘教，謂釋迦身也。初謂佛所見身，次是菩薩所見身，後是二乘所見身。又初是法身，次是應身，後是化身。第四門聞一乘了悟始終教意，具有三身，故《法華論》釋〈壽量品〉具明於三身。

They possess the three bodies. First, it explains that abiding on the ground of the dharmakāya, seeing that beings have suffering and no joy, he gives rise to great compassion. Next, at the time of his initial attainment of enlightenment, he expounds the Avataṃsaka teaching for the bodhisattvas; this is the Rocana body. The third approach is expounding the triyāna teaching for the śrāvakas; this is the Śākyamuni body. The first refers to the body seen by the Buddha, the next is the body seen by bodhisattvas, and the last is the body seen by those of the two vehicles. Furthermore, the first is the dharmakāya, the next is the saṃbhogakāya, and the last is the nirmāṇakāya. In the fourth approach, upon hearing the ekayāna, one completely understands the teaching's intent from beginning to end, possessing all three bodies; therefore, the Fahua lun in explaining the 'Lifespan Chapter' fully elucidates the three bodies.
