Clarity of Spells: For clarity sake.

Spells are Safe and yet so effective: no back fires or bad karma. 

we only call upon The Great spirit which is the God of gods.

We dont directly call forth any other Diety, Cosmic force, Spirits or universal energy.

The Great spirit has power over, controls and dispatches energy & lesser gods to serve us.

Its why our spells are so effective and safe: 

no back fires or bad karma.
