Jakob Bohme

If we incline our wills in true earnest singleness to God, then we go with Christ out of this world, out from the stars and elements, and enter into God; for in the will of reason we are children of the stars and elements, and the spirit of this world ruleth over us.

This opinion, however, is held by most, that the devil was an angel, and that, having become an apostate, he induced as many of the angels as possible to fall away with himself, and these up to the present time are called his angels.

Sometimes the routes leading to feelings of anger are so convoluted and circuitous that it takes enormous skill to discern their original source, or fountainhead. But regardless of the reason for or the source of the anger or the relative ease or complexity in perceiving either the anger or its source - everybody, but everybody, gets angry.
