Question: Who or what is the “Light that Reforms?” Is it the Creator?
Answer: The Light, the Creator, the Upper Force, are all one and the same: the integral force of bestowal that governs the world, the enormous sphere inside of which all of us reside. Today, it is increasingly contracting above us, affecting us with its might.
It is regarded as Nature or the Creator since in Hebrew, a numeric equivalent (Gematria) of these words is the same, and emanation expanding from it is defined as the Upper Light or bestowal.
