Allow me to reflect on this word;   SURRENDER.    The first thing that comes to mind is acceptance.   Surrender to a condition, place, predicament, conflict is to accept it.  Not to judge, ignore, or feel the pressure of having to find a solution.

Release of anxiety comes from Surrender.   Think of an item that you wish release from.  Surrender your anxiety about this item to your higher self.   Realize that the burden will be dealt with in such a manner that your worry could not consider.
