Bringing yourself back to your heart centre whenever you catch yourself judging self and others--is the key to becoming a 5D human. Each time we do this along with changing our negative thoughts, feelings and actions to positive ones,we re-programme our subconscious mind to living in the heart or 5D.
The mental body is connected to the physical body and the emotional body to the spiritual body. In making the shift from 3D to 5D and beyond we must go through 4D and the only way in doing so is through the emotional body and the highest emotional expression being--love. In other words we cannot intellectualize ourselves into enlightenment and ascension, we must--feel our way.
