大般涅槃經義記 9.4

9.4

In the second section, it first clarifies that the Tathāgata, pitying these sentient beings deluded by heterodox teachers, extensively invited the bodhisattvas to roar the great lion's roar. From "Although in emptiness" downward, it clarifies the reason for gathering the bodhisattvas to roar. From "The lion's roar speaks of all" downward, it sets forth that which they roared: "speaking of impermanence and non-bliss" delineates the phenomena of saṃsāra; "speaking of the Buddha as permanent, etc." reveals the dharmas of nirvāṇa.
