You manifest what you fear.
- Sri Bhagavan
The mind has the nature of believing things. What you mentally project unconsciously in the future, makes things happen in your life; both, Good things & bad things. But since mind is generally inclined to the negative & also due to the charges driven by our past painful & unpleasant experiences, the effects of negativity is more... such as our fears, hatred & destructive mind tendencies.
The unconscious mind is so powerfully controlled by it’s beliefs that it makes them your reality in the near future.
So, stay conscious of your fears. Find their root cause. Take divine help & make peace with them & solve your issues.
