If everyone is an extension of the God-Source in manifestation, why would you fear another?  Only if it is part of the roles you are playing.  But if you do not like the feeling of fear or any of the lower vibratory emotions, then see all others and yourself for what you are:  souls playing roles.  Instead of focusing outward on the roles, turn inward to where all are souls.  Then, keep going in, in, inward to the state of Pure Awareness from which all arise.  There you find your oneness.  How can there be fear at that level, where there is no differentiation? Choose your point of view well, and you will have chosen peace.
