A must for madness

In the shells
Safe are all secrets
Except the ones
Told by the sea

In the brink
Of madness
What shall we do?
Except carving mirrors
Stubborn and erect

In the pale light
No love is as dark
As my dead kitten
No regret in me either

When everything else
vanishes, sands persists
So do the mind devoid
Of words and lyres
