Radically Happy

Finally, I glance at where my side was pierced, where I see that a hole still exists. I gently probe it with my fingers, and am surprised to see that the hole looks like it extends all the way to my heart!
Yet, it is positioned in such a way that I cannot see into it, though someone standing beside (and below) me could.
I look for something to fill the hole, but there is nothing else in the cave. I’m sure I could find something Outside that would close the doorway to my heart; but, should I?
