DISSOLUTION OF THE BARRIER

The spiritual heart, the invisible counterpart of our physical heart, is the centre of our higher self. The head as the seat of the rational mind is the centre of our Ego-self. By submitting ourselves to the voice of the heart, the Divine intuition, we are following the Divine will and love for us and are contributing our best to the sum-total of harmony. Whereas in allowing the Ego to rule our lives, we are only looking after our own lower selves and are usually working against the well-being of the sum-total of all existences.
In young children who have not yet developed a personal Ego and have not yet had the opportunity to experience fear, the heart and the head are still closely linked together and it is the heart which is the centre of their existence and its voice is leading their actions.
For as long as the heart and the head are in connection with each other the individual is in a state of inner harmony and in harmony with the whole of existence.
Fear is the cause that is creating the rift between the heart and the head. The greater this rift is the more the Ego feels the need to fight for itself and the less personal harmony is possible, the further removed is the "I" from the true Self and its natural connection to the Universal  source of love.
All illnesses are created by fear and by the inner disruption of the love link between the higher and the lower Self.
Therefore, true healing can only happen if the fear that is keeping the Ego isolated from the heart and its power of love is being removed, i.e. dissolved by love, acceptance, understanding, awareness in and for the own Self. Thus the link between the two parts of your being is being recreated and harmony can re-establish itself naturally.
