You could donate your organs to someone else if they need them and you do not. Some people will actually get their driver's license or identification card to say that the owner is an organ donor which means if they die in like a car crash then their organs would be donated to someone else. You might want to consult your local hospital for more information on organ donations. This website can't properly offer information like that nor is this a site-related question.
It is a site related question because I know about donating organs but I wish to know about it spiritually as if someone have shorter life, written in their fate and spiritually one wish to exchange that fate means one wants one's longer life reach to one having shorter life span then is it possible? Because I have seen such thing in real also. Once when I was so little an uncle of mine donated his life span to his child, to let him see the world more as some priest told him that his child will not live longer and when he asked priest for any solution, he asked himto donate his part of life to his child and it happened. I had heard about it so wished to know. Its not going to harm anyone, its a good thing I have seen. I just wished to know about such thing if anyone knows about it.
indeed. You could do something like energy exchange, the exchanging of your energy into anothers aura to boost them temporarily and that, if taken too far, can kill you, but actually donating your life in essence is no where near possible to my knowledge.
Even twin rays can't do that. They can keep one another alive if extremely injured for a while, but they can't donate life...
Thank you so much for your valuable responses. Its just a curiosity to know if anytime someone in your family or anyone special gets into some critical condition and as it is necessary for them to be alive then can anyone help out in this, who don't feel their life of that worth in comparison to them or have pretty longer life. Such major incidents are also often seen.
