Entering detachment, the medium becomes wholly neutral. The discipline is rigorous, volitional and everyone can do it. Spiritual egalitarianism is inherent. The interconnected universe in which everything is made up of energy vibrating. We-everything are energy forms continuously communicating, telepathically and otherwise.
Accurate precognition demonstrates the method.
Quantum physics opened that closed box and recognized the fundamental continuity of all that is. Thus, we enter any person or scenario wherever it vibrates by temporarily mimicking their form. Frequency change, not 'angels', allows us to access information from any form we lock our attention onto. I suggest the next leap in human consciousness entails everyone actualizing these stunning potentials. Marlene Hanna could see the future when she was four, but never saw an angel.
