Fourth Layer (The Astral level)
This is the true bridge to the spiritual plane! When we start to work with this plane, and above, our perception and abilities leap from the physical to the subtle. Here we will begin to perceive energies that are not of this vibrational frequency ie Beyond ones Body.
