From the Abstract
Entering the Dharmadhātu compares the complete set of panels with three early Chinese translations of Central Asian and Indian Sanskrit manuscripts of the Gaṇḍavyūha. This first identification of the entire series in English concludes with a discussion of the new perspectives on the meaning, symbolism, and architecture of Borobudur that a reading of the Gaṇḍavyūha suggests.
