In the physical world, you use a barrier when you apply a toxic substance to another object.  Perhaps you wear a glove or use a brush.  Why is this?  For the flow goes in both directions.  You do not want that toxic stuff on you or in you.  Flow is everywhere, dear friend.  When do you put up emotional barriers?  Much of this is learned behavior.  You recognize toxic energies when you feel them.  Watch out for the energetic barriers.  Be careful not to block them, but to let them pass right through you.  Set the intention that no energies will harm you, but simply allow you to make soul-based choices how best to respond.  Once the blocking begins, even the loving energies may not flow, therefore, dance with what presents itself and be free. 

You are so very loved.
