It has been well known in biological sciences for some time now that you are a product of your genes - that is, except when you are not. Epigenitics, we now know, governs which genes are allowed to express themselves in our physical bodies.
Here's a quote from the recent Time article on the topic (http://www.time.com/time/health/article/0,8599,1951968-1,00.html
"At its most basic, epigenetics is the study of changes in gene activity that do not involve alterations to the genetic code but still get passed down to at least one successive generation. These patterns of gene expression are governed by the cellular material — the epigenome — that sits on top of the genome, just outside it (hence the prefix epi-, which means above). It is these epigenetic "marks" that tell your genes to switch on or off, to speak loudly or whisper. It is through epigenetic marks that environmental factors like diet, stress and prenatal nutrition can make an imprint on genes that is passed from one generation to the next."
So genes can switch on and off according to environmental factors? And these states can be inherited? I was taught in school that we were a slave to our genetic code, that you were dealt certain cards in life and just needed to accept it. Now we know that even our genetic code can be modulated by the environment.
Now the big question is - can genes be switched on and off by states of mind or emotion? This could explain a host of phenomena from spiritual healing, cancer remissions, and who knows what else. Mystics have long held that transformations of consciousness can also transform our physical bodies and conditions. Skeptics have shot down such notions repeatedly.
I expect that, in this case, the skeptics will end up eating crow...
