Organ transplants became feasible after Immuno Suppressive drugs (current Trade Name - Cyclosporin in India, in other countries it may be different) came into being. These drugs reduce the effects of the immune system of the body so that it does not reject the foreign organ. But the surgery increases the chances of infection in an artificially weakened immune system, so a very strong dose of anti-biotics is maintained for extended periods to ensure transplant is successful. It is a very complex procedure. Each of the drugs have severe side effects and their combined effect cannot be evaluated as it varies with each person. After transplant, the physicians try to ensure that the biochemistry of the body which allowed the organ to fail, does not happen again and prescribe more medication together with lifestyle management adjustments. All of this have grave psychological aspects. Add the extended stay in Hospital with together other people in a state of depression and the free time to contemplate on events in life.Certain changes in psychology of the eprson is expected and natural. For example for a person who has been very active in life, has to slow down his pace. And if he learns that the transplant came from a lazy person which could be pure coincidence, it will be easy to conclude for him that it is due to a transplanted organ. This is based on a real story.
Many of the drugs used in the treatment of cancer have severe side effects of producing the symptom of depression and other psychological disorders but those are not listed. Treating physicians know this from experience but will not tell. This is another story. I am looking for a person who received organ from a very active person like an athlete or a politician and became like him.
I confess that I do not understand the cause and consequence based karma theory very well. But for those who believe in it it would be logical to assume that it is the effect of good karma which has made the continuation of life possible through transplant.
Certainly, the immune repressing drugs given in transplant cases would elicit quite a few pronounced side effects. It may well be extremely difficult to separate those variables in any study done on transplant recipients.
In regards to my contention, and others, that it is the etheric body in the transplant tissue that would be influencing the recipient, the etheric body dissipates from the physical after bodily death. This dissipation rate probably varies from individual to individual, depending on many factors. Most likely, in most cases the etheric is absent or barely remaining at the time of transplant, so these cases would not be effected by it. It is in the rare cases where the etheric remains in substantial amounts that effects would occur in the recipient.
I don't know what the psychical research in this field says, but I doubt if there is much at all. Many people mistakenly think that any kind of scientific study, paranormal or regular, can be started at the drop of a hat. That's far from the truth of the matter.
Research costs money, big money nowadays. Much politicking, and in some case graft and bribery, goes into obtaining research money. And, the materialists control most of the money available, through government or private foundations. The parapsychologists and psychic research vie for the rest.
Some day this may change for the better and there will be a full, long term, solid study done on transplant donors and recipients by our most talented parapsychologists.
Reincarnation or any form of enlightenment or afterlife is a big topic with me. I try to look at this with facts and take into account the myriad of religions world wide. In order to understand a concept fully you need to look at it from a lot of angles. The idea of an afterlife, I feel, is human nature's way of dealing with the permanence of death. In Buddhism one strives to enlighten themselves through many reincarnations of life so that one can experience all there is in life. That is putting it simply without getting into a full page article on the intricacies of Enlightenment. In Christianity, one believes they go to heaven or hell based on their actions in life. Death, whether we like it or not, is a permanent event that will happen in our life (unless trans-humanism becomes relevant in the near future). Humans are built on a will to survive and most people will do what they need to in order to survive. Look at high crime areas in cities, although there are bad deed occurring, people are doing what they feel they need to in order to sustain their life. It may mean mugging people to get money for food or stealing from stores, etc. This will to survive has caused humanity to undergo a compensation mechanism with the fact that we will die. Buddhism tells us that one should be prepared for this event and remove attachments in our life. It has a very focused goal of helping people think outside of this genetic device that we have created and embrace death in a more practical perspective.
The truth of the matter is no one knows if even such a thing exists. You can have all the faith in the world but faith doesn't prove reality. Faith is a mechanism to provide hope in a world that we live in. In reality at one point we were all atoms floating in space after a massive star death. Now we possess this form. I think people should focus more on their consciousness and how to make an impact on the world they are in NOW, rather than racing to prepare for one they can not confirm exists at all.
