I understand how fear works but I do not know how to control it?
Unfortunately, the people of the world exist on fear as fear is a way to control. Our minds have been programmed since birth to accept fear, and our ego uses it to become the dominating part of us. Therefore, fear is very hard to control.
The replacement of fear is love albeit unconditional or emotional love.
Meditation is a great help in combating the ego so, if you are not doing meditation, I suggest that you take up some form as this is a way of suppressing and controlling fear. Your mind is taken to a neutral space during meditation where fear does not exist, and this will give you the space to bring in the energy of love from the source, “All That There Is.”
You could also look at reprogramming yourself through self hypnoses, and or creative visualization. However before doing this, it is important to ascertain what your basic fears are, and then work out a way to have a positive response to them.
