First you heart beats, so it is
Second, you can hear it
as long as it beats, you can hear it, you enjoy
don't let others distance, quietness or absence make your heartbeat less than the wonderful music of your world because you are precious, your heart is the center of that gem you are, wherever I or someone else hears your heartbeat. And know that, even thought you don't see or hear them, there is always someone who hears your heartbeat, maybe, you need to listen to hear their heartbeat.
Now, if it breaks, you can fix it, you can heal it, as long as it beats.
Love and peace on you and all
