Karma yoga
The path of balancing the yoke of karma—of causes and effects set in motion in this and previous lives; the path of good works evidenced in pure thoughts, feelings, words and deeds; the discipline of the four lower bodies with an emphasis on physical action for alchemical change; spiritual/physical exercises including the invoking of the sacred fire (agni yoga) in the giving of violet flame decrees (mantra and japa yoga); nonattachment to the fruit of action or to its reward. The end of the path of karma yoga is freedom from the round of rebirth through the Holy Spirit’s all-consuming Love and Grace, and reunion with God, the Mighty I AM Presence, in the ritual of the ascension.
The path of karma yoga shows us how to be in the world but not of the world. It shows how we can stop digging ourselves deeper into the mire of the human ego and instead work toward becoming a pure crystal through which the Atman can shine unobstructed.
Karma yogis must follow basic moral rules, never think evil thoughts, control their desires and passions, and never harm anyone mentally or physically. The karma yogi must never do work out of selfishness or feeling that he is making a sacrifice or a great effort. Krishna says that such work is impure. We must use the work to become detached from the world.
