What is the essence? It is a consicious essence. An inner experience. Most familiar to you. Your Soul, your very essence of being and knowing about it. Without knowing there is no existing. What you don’t know does not exist. In you there is the source of all knowledge.Your soul attracts all kinds of energy that it is compatible with. It repulses energies it is not comfortable with.
Your soul is like an onion, with many layers. The innermost layer is purity itself. The outermost layer exists in the field of duality, of right versus wrong, of good versus evil, of high versus low.
The only experience worth having is the innermost purity of your essence. This is a blissful and knowing experience, timeless also.
