The broken shards of the first tablets are stored in the ark together with the whole ones.—Talmud Bava Batra 14b.

When you find the Infinite, where will you put it?

In your broken vessel?
It will not stay.

In a new whole one?
It will not fit.

Let the heart be broken in bitterness for its confines. Let it be whole in the joy of a boundless soul.

This is the secret that the human being holds over the angels: Only the human heart can be broken and whole at once.
