What criteria would be useful to consider in deciding about the wisdom of receiving a transplanted organ?

As with blood transfusion, we would recommend the opportunity be used as an exit point rather than prolong life artificially and create additional negative entanglements for the person with the health problem who would be a recipient, but we understand human nature will rarely embrace this recommendation. There are not likely to be ways to do better matching of donor and recipient. There are many, many aspects to the karmic history of the donor that represent liabilities for the recipient. This will not be appreciated for a long time to come, and would often be viewed as politically incorrect in many cases, being a form of discrimination, in fact. However, it is a complex issue that plagues humanity in other settings as well. For example, adoption of foster children of unknown lineage being so risky with regard to prior history in the possibility of taking on huge karmic burdens within one's family. To be sure, adoption is a noble and loving gesture and we would not want to see it curtailed, but are simply pointing out that karma is very real and very important in the scheme of things, and it all traces through consciousness as contained within and manifested through, matter and energy, primarily within the genetic material of the cells and body, with the DNA being the translator of these energies in many cases.
