5.169

佛身即真身也。以法報合論、理智無二故。若欲分文別指，則佛身是報，大菩提法為法也。

The Buddha-body is the true body. This is because the dharma[-kāya] and saṃbhoga[-kāya] are considered together, and principle and wisdom are not two. If one wishes to divide the text and refer to them separately, the Buddha-body is the saṃbhoga[-kāya], and the dharma of great bodhi is the dharma[-kāya].
