"Do not be afraid; allow the Light to empower you!" ...
Fear is one of your root emotions.
Do not feel alone, everyone in the world experiences this. An infant child, upon not being able to find its mother, will be afraid that is has been abandoned and may soon die.
Fear is often experienced viscerally, including physical sensations like chills, body tremors, sweating, nausea, dry mouth, or pain.
An ancient Japanese proverb says "fear is only as deep as the mind allows", and it is so. You can choose to be courageous, to face your fears, at any time. Know that when you decide to let Divine Light into your heart, at that moment, you will be energetically invincible.*
