Your Higher Self is, in simple terms, the highest aspect of you that can be attained and held in the physical body. It is the part of you that knows, sees, and understands at the highest level possible, while the physical part of you still continues to move around in the third dimension. Anchoring the wisdom of the Higher Self into your physicality is very much a part of our human spiritual evolution and purpose.
This amazing time of Shift is adding to how you experience both your Higher Self and your Soul. As you begin to remember yourself and return to higher levels of consciousness, aspects of you and the Higher Self are going to merge very rapidly. As you begin to experience yourself as the merged Higher Self, greater levels of knowledge, wisdom, and understanding that the Higher Self IS begin to be who you are.
