Fear is an alarm signal of the conscious mind… so as I see it… it’s only purpose is to supercharge the body to react to any energetic stimuli which it determines if life threatening..
Transitions are the process of energy being increased, reduced or re-aligned which can be stimulated by fear but it is not itself an actual part.of it, rather an outside force creating a reactionary experience.
So our self transformation, either positive or negative, can be stimulated by fear. However if we hold onto the fear as having a value during the process we will not make the transition completely.
Which is many times why we have remnants of shame, guilt or self-doubt even after the transition has been completed. Which will in turn have us repeat the same task over and over again.
