The universe is energy. We are also energetic beings. Our energy is generated inwards and flows outwards, towards others. Your strengths or weaknesses, generated by your thoughts are reflected in the world around you.
Metaphysics teaches us that we are responsible about our reactions towards others, and the energy we generate. It teaches us to understand this energy by understanding ourselves, our fears and our emotional responses more deeply.
The focus becomes about understanding ourselves on a multi- dimensional level. If our life is not working, we need to invest our efforts into correcting/replacing our negative thoughts and accepting our life and circumstances.
Purity means acceptance. Accepting life, the way it is. And loving life the way life is. Be the positive, loving, truthful, higher you.
