The realization is that any negative feeling pattern, such as fear, is caused by a belief in separation from the Divine Self. The individual, by authority of Divine will, is ever free to make a higher choice at any time, and the power of commitment to do so is the way of permanent healing. So by getting still and stating the word, the pattern is healed, and the Soul is freed, forever. I cannot say how powerful and authentic this is. This question immediately causes higher vision of Divine attitude and knowing to spring forth.
All reactivity is separation.
Our Divine birthright is peace and bliss that comes from perfect knowing in all situations.
