A Beating Heart Part 2 {Quatrain}

I know, it is short, and some do not like short... But, it was written for a contest of only four lines.
---------------------------------------

A sample of heart is not deep beneath the chest,
Held in your hand is your heart to be behind the breast.
Squeezing tightly to your majestic treasure, you will not lose,
Unless letting go of your heart is what you choose.
