The feeling of unworthiness only comes from our personality, (our lower self). When we accept the wholeness and the connection with our Higher-Self, this feeling cannot subside. Yet, when we are feeling separate it can produce intense fear, as our emotional body is connected with the astral plane of the earth. These fears move in waves throughout the planet and affect all life, human or sub-human, on that level.
You can help yourself and others by invoking protection from your higher-Self. If you place your sense of power outside yourself, looking for other’s approval or believing that you need to reach a certain material status to have value, you lose your own sense of power. When you retain your power through your connection with higher consciousness you become an active channel of Grace and Blessing for yourself and everyone around you.
