Whenever there is any energy that imbalances, i.e. fear, terror, doubts, torture, illness, danger, etc., the imbalanced energy will attract Outsiders and Parasitic forms.
Even when one is consciously doing personal healing work, when old patterns, memories, emotions are triggered, the old will imbalance the individual's energy field.
It is CRITICAL for those in the situation and EVEN MORE SO FOR THOSE OBSERVING, to Call in the Spiritual Healers, Guides and Mentors and ask that they create strong boundaries to cocoon the individual/s. In addition, declare the qualities to be broadcast into that cocooned space, i.e. Vitality, Wisdom, Love, Balance, Clarity, etc.
