Steve, that's all fascinating stuff, but I'd like to see a few scientific credible sources...
Mccoy I’d like to ask you one personal question; can you tell me why you practice Kriya yoga daily when there is no scientific evidence that it burns off Karma?
Steve, the answer is simple. If we are discussing some physical entity, then the laws of physical science, which is pretty sophisticated now, should apply. For example, astronomy has reached an incredible level of sophistication, the Pleiades being a rotation hub for some part of the galaxy should be a well-known truth, but apparently, there is no hint of it. It has not been observed. A simple, detectable physical phenomenon that is lacking physical evidence is very suspect.
On the other side, karma, meditation, kriya yoga, and religion, are concepts belonging to the metaphysical sciences. There cannot be scientific evidence, since this is not the domain of physical science. Other parameters apply, like logic inference, intuition and so on.
