大般涅槃經義記 8.98

8.98

第二相中，啟化之初名為「晨朝」，從德現化稱言「出穴」，現通摧慢名曰「頻申」，許說進善義稱「欠呿」，照察物機名「四顧望」，初陳法化名為「發聲」，法響踰盛故曰「振吼」。

In the second, the signs: the beginning of initiating transformation is called "morning"; manifesting transformation from virtues is called "emerging from the cave"; displaying spiritual powers to crush arrogance is called "stretching"; agreeing to speak and advancing goodness is meant by "yawning"; observing the capacities of beings is called "looking in four directions"; first expressing the Dharma transformation is called "uttering a sound"; and the resonance of the Dharma becoming ever more magnificent is called "roaring."
