S/He Dragon follows song lines, those moments in time that touch ground and open doors or not. Song Lines keep S/He moving in an upward spiral. The following verse from the Holy Bible, King James Version, Job 38:31 feels like song lines:
Canst thou bind the sweet influences of Pleiades, or lose the bands of Orion? Canst thou bring forth Mozzaroth in his season? or canst thou guide Arcturus with his sons? knowest thou the ordinances of heaven? canst thou set the dominion thereof in the earth?
