It is not uncommon for people to relate a sense of fear at the recognition of their essence as pure awareness. A person can then feel the fear is a block they must work through. In reality, however, fear is just a thought tied to an emotion like any other thought. A thought only has what power your belief in the thought gives it. If you believe any thought, it can seem to be a stumbling block and fear is no different.
The suggestion would be to view the sensation of fear, or any other emotion or thought, as a grace not a barrier. The recognition of the sensation gives you the opportunity to look at who or what is seeing that emotion. It gives you a direct pointer back to your essence. Clearly what you are as vastness, silence, awareness, presence, etc., is not disturbed by any thought or emotion. Namaste, Steve n Bec
