Karma means action in Sanskrit, and Karma Yoga is the Yoga of Action.
There are a few ways karma yoga can be performed according to the traditional scriptures, but one of them is to set up the concept of a personal God, an all-powerful entity that is responsible for everything and every action in the universe. The Karma yogi is taught to realise that it is this God (sometimes known as ‘Ishvara’, which literally means the owner, ruler or controller in Sanskrit) that ultimately has control and not the limited body-mind that it thinks itself to be.
The karma yogi therefore practices gladly accepting everything that comes his or her way as a gift from God, working to the best of their ability, but not being attached to the results of their actions.
As the Karma yogi starts to learn to be happy regardless of what is happening, this has the direct result of eroding away compulsive desires, converting them into non-compulsive desires, and so eventually the yogi becomes peaceful and pure (sattvic)
Thereafter, over time, the sense of identification with the body-mind entity loosens and is seen through. It can become apparent to the Karma yogi that actions happen by themselves: thoughts happen by themselves, but there is no thinker, just a spontaneous thought occurring, one by one, in quick succession. Similarly actions happen by themselves: limbs move, lips speak in the same way that dogs bark, leaves rustle and clouds float by – all happens spontaneously, and there is no doer. Here Knowledge arises.
Now the yoga has completed its aims: Freedom has been realised and we are seen to be free from suffering – we are seen to have always been free from suffering and the world. Now we no longer have to worry about concept of an infinite all-powerful personal God that is ultimately unknowable and unverifiable.
Again, the concept of the infinite God, as with the concept of the Unchanging Indestructible Brahman for Jnana yoga, can be seen to have been a useful tool, aiding the seeker to attain Liberation, but now no longer needs to be believed in.
