佛祖統紀 3.61

3.61

The seven locations and eight assemblies are from the older sixty-fascicle sūtra translated by Buddhabhadra under the Jin, which Tiantai cites. In the newly translated eighty-fascicle version translated by Śikṣānanda under the Tang, an additional assembly at Universal Radiance was added, making seven locations and nine assemblies, in thirty-nine chapters. Only the chapter on Asamkhyeyas and the chapter on the Light from the Secondary Marks were preached by the Buddha; the rest were all spoken by various bodhisattvas under his empowerment.
