A bottomless heart

CLAVIS INFERNI aka 44th Of The Great Keys Of Solomon...
Is Within In Us All...

The Three Nails Represent:
a) The Crown aka Mind
b) The Noose aka Throat
c) The Breast Plate aka Heart

When You Use The 44th Key... Correctly... You Strike All Three Notes On The Demon Tormenting You. They Retreat.

Spittle Builds Up In Their Throats... Profusely...
Their Heart Plummets And Pounds... Thunderously...
And Their Mind/Crown Is Bombarded By A Powerful Spirit... Wholely.

This Key Is Notorious For Breaking A Spell... Or Bruising A Witch.

I Can Say No More
