新華嚴經論 8.56

8.56

第六會在他化自在天宮者，為於此天說其十地，為其此天以他變化用成己樂，以明十地大悲大智皆悉成滿，但化眾生以為自己涅槃之樂，無自樂故。

The sixth assembly is in the Paranirmitavaśavartin Heavenly Palace: because in this heaven he explains the ten grounds. Since this heaven uses the transformations of others to constitute its own pleasure, this clarifies that on the ten grounds, great compassion and great wisdom are both perfected and fulfilled, and one merely transforms sentient beings to constitute one's own bliss of nirvāṇa, having no pleasure of one's own.
