I have thousands of essences for use with my clients, but the Australian Bush Essences, are some of the most frequently used.
I add several drops to my glass or water, or even add them to my bath water.
Here are two of the best for cleansing and protecting your energy:
Angelsword
Protects you from outside influences, and helps discern what is yours, and what is not. It also cleanses your aura after stress or shock.
Fringed Violet
Repairs the aura, and realigns the subtle bodies after shock or trauma.
