Ever notice,
How when you try to become a better man LIFE all of a sudden becomes difficult?
This is not your fault it is quite simply, the work of what is religiously known as the devil.
Evil in our world has always been depicted as demonic by way of a single overarching entity, that influences the dark temptations that pull on you and me.
Why he has been depicted as a red, horned, serpent tailed beast with a pitch fork is not entirely clear, because the devil does not appear in this form when we are pursuing the nature of our highest expression.
