"When the sound is gone and the hearing is perfected, and all-pervasive power of compassion arises, and I can make it so that if living beings are travelling a dangerous road, thieves will not rob them." "When one is permeated with hearing, one separates from worldly objects, and forms cannot rob one. Then I can make it so that living beings with a great deal of desire can leave greed and desire far behind." But only when She contemplates on the sound and separates Herself from the physical body.

That is the response body.
