Around our pillows golden ladders rise,
And up and down the skies,
With winged sandals shod,
The angels come, and go, the Messengers of God!
~ Richard Henry Stoddard
There are lights which ascend and lights which descend. The ascending lights are the lights of the heart; the descending lights are those of the Throne. The false self is the veil between the Throne and the heart, like springs toward like. Light ascends toward light and light descends upon light, and "it is light upon light."
