Colossians

Paul’s Epistle to the Colossians is closely related to his Epistle to the Ephesians. Even a casual reading reveals many similarities, and some passages in the two Epistles are almost identical; but there are also several marked differences. Metaphysically, the Colossians represents our thoughts in our Consciousness pertaining to the activity of the law of sowing and reaping (what we often refer to as Karma).
