Dear Renuka,
Religiously/spiritually it is believed that if some one donates an organ as intrinsic to the body as Heart, the recipient of the organ will have to return the favor in the donor's next life, as per the principles of Karma. That means, the donor will have to have a next life. This can be a hinderance to both the person (donor & the recipient) to get liberated from the cycle of rebirth.
At the same time, since Hindus believe that the physical body is nothing but a mere machine that is left to be disposed off once the soul is out, there is nothing wrong to let others benefit some way from this body, discarded by the soul. And that, it would be a selfish thought and act to not to donate the organs of the body to the needy so that one need not to have next life, in order to receive something in return of the favor from the recipient, who had committed upon himsel/herself to receive and pay back.
In this context, I would buy the following observations of yours in your post #2 -
"Something cannot really be explained..so I am starting to wonder if the human mind leaves a imprint in all organs like a cellular blue print and when the organ is used by another person these cellular blue print is activated and similar behaviour patterns of the donor is seen."
Adding to the above, I would speculate that, the recipient's mind too would leave an imprint in his/her received organ(s) as well and synchronizes well with sort of indentification tag without any lapse such that, he/she would end up paying the favor in return to the same donor, in his/their next life.
Shri Yamaka,
As far as the issue highlighted in the ariticle is concerned, I am of the opinion that, the legal/medical regulations should be such that, the relative of the donor should have the final consent to proceed with harvesting, if he/she is convienced that the donor is dead or can be given up, considering impossibilities of the donor's natural survival. And to be proved that the donor was administered with fentanyl and sufentanyl anesthetics, before harvesting, considering his/her brain dead, when medical specialists could not substantiate unanimously that the brain dead would not react and feel the pain.
