One day God spoke to Moses and said:
'Visit Satan, question him, use your head.'
So Moses descended to Hell's burning halls;
Satan saw him coming, a smile did he install
On his fiery face. Moses proudly asked him
For advice, waiting for Satan's crafty whim;
Satan spoke through his coal-black teeth:
'Remember this rule which sense bequeaths
Never say "I" so that you become like me.'
So long as you live for yourself you'll be
A drum booming pride a cymbal of infidelity.
Vanity, resentment, envy and anger shall be cemented
Into your inner state; you shall be like a demented
Dog with lolling tongue, infected with indolence of sin.
You shall become your own tracked prisoner within.
