Rejection, go a different Direction.
As a baby we have one fear, we fear being separated. This is a survival mechanism, for if we are separated from our mother - we will perish. Though this is not necessarily so today, in our civilized world, this fear of separation is still inherited from our past. While we are attached to an outer object (mother) and while we are in the womb, we are protected and safe. When we enter the world and are free from our safe womb, we still need the attachment of this same outer object. For we have changed little from being in the womb, we can breathe air but we are even more vulnerable.
