Gurudev, how can we control fear?
Fear is what you feel when you think you have no support. When you feel separate, you feel fear.
There is a beautiful saying in Sanskrit, 'Dvitiyadvayi bhayam bhavati'. Fear happens when there are two (meaning when there is no feeling of belongingness). We simply need to recognize our origin, our source and get connected to our higher Self. Then fear simply vanishes. It only needs this recognition that, ‘The Divine loves me very dearly; the Infinity is with me and all of Nature is a part of me. There is someone to care for me’.
Just these thoughts and positive affirmations are enough to make that fear run away.
