The language of the heart is silence. In the silence which is heart-centered we find our inner strength; we can listen to the inner voice, the voice of the spirit which will guide us and help us understand the needs of others as well as ourselves.
When we enter the chakra of the heart our world changes, we see and hear more clearly; touch and react more sensitively, all our senses are heightened as distinct from those which are necessary for survival i.e. gut reactions through the senses.
Someone who is heart centred does not need many words; they have no need to hide away behind words. You see truly who you are, pure Divine spirit.
Devotion springs from a pure unselfish heart, devotion to the Divine and seeing the Divine in all things.
