You may be afraid to let go of something because you fear nothing will come to take its place.
You may be afraid because you've been holding on for so long that you've forgotten how to let go.
You may be afraid to let go because the one who has been holding on is who you have been, and who will you be if you're not that?
All questions about letting go have to do with fear.
All answers have to do with love and trust.
The Unknown is not empty. It is a vibrant, alive, full Unknown, filled with love that comes from God and is God.
Instead of picturing an empty space where something was, picture a space that is alive and pulsating. Now, it is covered with a veil. When you enter it, the veil will be lifted.
Then, a new empty space will be created as you continue to move into the future.
This is the path of new creation. It is how one becomes free. It is how humanity will learn to flow with the Divine movement of life.
