The Vacated Space
Herein lies the secret of the vacated space. G-d’s light was everywhere, yet He carved out a "vacated space" to make "room" for creation. So too we must "make room" for a "good creation" in our heart, into which G-dliness can enter and dwell. This we accomplish through thinking good thoughts, bringing about a good creation—a higher and better level of consciousness. Then we can merit an even greater revelation of G-dliness. In fact, when we turn our hearts into a vacated space to receive G-dliness, then simply by thinking good thoughts we have formed a new creation.
