If we do not address our pain head on as it arrives, we repress it by self medicating with almost anything and everything such as drugs alcohol, shopping, gambling, relationships, etc. We then spend the rest of our lives trying to access what has eventually become unconscious within our subconscious, with shadow work (Therapy of some kind) so that the heart is purified, thereby allowing our Conscious Mind (thought) to rest in the Peace that a loving heart aka Subconscious offers.
A peaceful heart and mind is a channel for Spirit - for intuitive guidance.
"Blessed are the pure in heart, for they will see God." Matthew 5:8
