This is a yes or no question :-

1. Before we facilitate healing to others, the mind shall always keep in the state of “positive” & “loving”, if we have a thought form like fear of negative energies being transmitted, we may attract negative energies as the mind manifest it.

2. We may have blocks or similar issues to the person we are treating, this may have tendency to trigger the issue hidden within us, and we thought of we are being “attacked” by others.

3. Call for protection like golden dome of protection, imagine you are inside a golden bubble of light, and no other discordant energies can penetrate in.

4. Invoke angels (Archangel Michael etc), guides, ascended master, healing master from the light for guidance and protection during the entire session.
