When you experience negativity of any kind or its cohorts: fear, anxiety, worry, stress, insecurity, doubt or anger is an indicator that you are disconnected from your higher self, your spirit and your intuitive guidance. The way you know this is happening is you have the stress, chaos and dysfunction in your life to show for it.

Psychic armour is an energetic shield or force field we can consciously call upon to combat any fears, anxieties and insecurities we may have, as well as making us immune to external negativity that sabotages our highest intentions.
