Then Sell Your Soul

There is a silent death we die,
a spell we dare not say.
If nothing I have said will fly, 
then you must go away. 
I cannot make it clearer than
what the ancient language can. 

So sell your soul now, if you must, 
if death is all you fear, 
to greed, estate, power, and lust, 
but shun then every mirror. 
You must not look upon your face
and see what lives there in your place.
