The expansion of awareness from third through fourth into fifth dimension means we are also developing the sense of directly feeling Energy in Motion or e-motion rather than just witnessing it.
To assist this forced process, we need to remove the restrictions kept in place by the survival mind / ego self which is designed by evolution to respond solely to the five senses. It presents a fear response to anything outside of this.
To move the mind awareness into fifth dimension, the only way forward is to dissolve all lower vibrational energy in motion which is far slower and denser in nature. The difficulty is in letting go of all we know ourselves to be – but this has to be done so we no longer react, retain / store / hold lower vibrations in our lives.
Without consciously making this change, the body will experience extreme difficulties with the changes as the denser energies will stagnate into illnesses affecting the organs and endocrine systems. In particular, increased vibration as cellular activity will create over heating, exhaustion and nerve failure of the mitochondria.
