Unstruck chakra

In Sanskrit the fourth chakra, or heart chakra, is called the Anahata chakra.  Anahata translates as “unstruck” and sometimes “unhurt” and I’ve been wondering for some time why it was named this.  I’ve found a couple of interesting explanations.  The first is that somewhere beneath each of our individual stories, which often include some sort of pain and hurt to our heart, there is a wholeness comprised of unconditional love and compassion which is “unhurt” and just buried waiting to be found.  The second explanation is that the Anahata chakra is positioned at the place in our body which is responsible for producing the sound of our own vibrations.  This sound is produced without anything being struck.  And the sound, of course, is the sound of our beating heart.
