Two questions for you, a comment with third question related toQ1: Are you thus stating that non-material "karma" modifies the discharges of nerves in the brain, causing them NOT to be coverned by the natural laws, which science attempts to understand? I.e. thought, choices etc. proceeds under the influence of continuous miracles? (Only one question , stated twice to be clear.)
Basically, yes.
Q2: Again I define a miracle as a violation of the natural laws that scientist postulate/ believe control ALL material changes, nerve discharges included. - Is that your definition of a miracle also? And again, please note that the accepted "laws of physics" are not identical with the partially un-known "natural laws."
I don't concern myself with "miracles", so I can't comment on this.
To believe in Karma being effective on matter, you must be rejecting the concept that the material universe, human brain included, is controlled solely by natural laws.
Q3: Is that your POV? -(or have I misunderstood? -if so, please try to state more clearly so I CAN UNDERSTAND.)
This might come as a disappointment, but I will bow out at this point. I have been using these discussions lately for myself to check whether and how I understand certain Vedic concepts about free will, karma, existence of a soul and Supersoul. I feel I have reached a limit here and that it would be best that I do not continue any further on this, at least not for some time.
Thank you for the discussion and take care.
