Soul is total consciousness. It has the complete knowledge,love, and power that all men seek, yet few relize that these qualities are within themselves.They look to the outer instead of the inner self
In Eckankar the road map to God starting to the lowest is 1= phisical plane 2 Astral Plane 3= Casual plane 4= Mental Plane& Ethoric Plane 5= Soul Plane the first spiritual plane or first heaven
Astro projection differs from Soul travel. Astro travel only goes as far as the Astro plan, ahere Soul travel can access all the lower planes to the spiritual planes of God
