Silver Sentinel builds three levels of aura boundary and protection making it more difficult for unwanted energies to intrude. Silver Sentinel also gives you more control over your personal energy space.  This deep level essence is a part of the Triple Application Set for protection by layered application. Silver Sentinel is applied 2 or 3 times in sequence, building layers that deepen and strenthen the effects. It is made especially for this kind of application. Be guided as to how you feel as to whether to apply 2 times or 3 times in succession as it can be rather strong!
