• Raise your vibration in just 8 steps – The Holistic Ingredient

    It is about energy, our personal power, our ability to attract into our life that which we manifest, that we deserve and feel worthy of. A few years ago my vibration was so low I was flat on the floor (with CFS). I felt totally and utterly stuck with no idea how to move forward. I was filled with a whole host of limiting beliefs that were holding me back no end. I seemed to be attracting ...
