If you wanted to study a plant would you go to the origin of the species or a hybrid? Similarly, where would you go to study a particular spiritual teaching?

The fundamental law of physics is that for every action there is an equal and opposite reaction.

Karma, literally, means action and action is caused by mental activity or, as I call it, menting.

The fundamental law of Karma is that for every ment there is an equal and opposite reaction.

So, every time our mind (moul) generates a ment the opposite is also generated and this continues until we cease to generate ments. 

We cease to generate ments when when the mind is finally stilled, when the moul has finally been eliminated, when all attachment is nullified and we have total non-attachment, and all that is left is the Spirit Self - that which was created in the image of the Great Spirit. 

This is the cessation of Karma, the cessation of birth and death.

This is Buddhahood, this is Christhood!
