Fear is the source of all sorts of miseries. Fear is a kind of Sin.
A fearless one only, can realize the Divine and manifest Divinity.
To annihilate fear one must know its root and should destroy that.
The root of fear is attachment and grasping attitude, and behind that there is belief of permanency of a thing/one, to which one remains attached. There one finds solace, rest, love and refuge. And the fear of loosing that, breaking that, missing that, creates fear, creates a sense of insecurity. This is the root cause of Fear. To destroy completely fear, one will have to destroy it’s root, all aforesaid substratum.
Wish you Healthy, Wise & Blissful Weekend!
