Though the head is above the heart in relation to the body, still the heart is above the head in reality. Decisions made in the heart rule over decisions made in the head. This is so because our hearts started beating long before we started breathing (inspiration brings thoughts) so the heart with its desiring/feeling had a head-start over thinking/rationality in the head.
When we are born our heads and hearts are one and work in unison, but as we grow older we learn to protect our hearts with our heads. For example many people with soft hearts act hard hearted so as not to be taken advantage of by the cold, mean or hard hearted. Plus some soft hearted people pretend to be hard hearted so as not to be perceived as weak or to be accepted. The heart is so soft and vulnerable it is protected all around by the ribs of the anterior and posterior chest. So everybody has a soft heart that pumps warm red blood.
The separation between head and heart widens as we grow older due to more and more layers of protection being placed on the heart. The heart itself doesn’t harden rather there’s layers upon layers of protection around the heart that makes it appear so. Then the protection that prevents injury to the heart, prevents us from knowing it also. The gap between head and heart can be so wide that many never realise their full potential, because they may take too long to figure out their hearts true desire and thereby not have the time do what they came here to do.
Growing pains as our hearts only open when there are shocks to our systems, like when we first started breathing and felt our lungs sting. It seems we learn the most from unpleasant, hurtful and shocking experiences as they make us much more self aware. At such times we may make a change, hopefully for the better, in ourselves. For when one delves deeply into the pain it’ll reduce the hurt and one can find the source. When we lose a loved one it could be among other things like waking up from a dream or falling into a nightmare with sorrow so deep it racks ones soul. Then we have to dig deeper into our heart of hearts and reach up to the Most High and open up the flood gates of tears and grief and wash our soul clean. And after the dark night of the soul comes a bright and sunny day to make us whole. So says my inner voice, which said to me yesterday while I was bicycling the tobacco trail, take care of yourself and it’ll be alright.
In conclusion, heart rules over head in every woman and man, for the above mentioned reasons given and many more that the kind reader can come up with I’m sure.
