Is organ donation allowed? Have any Hindu acharyas commented on this practice?
Organ donation yes may be done for the welfare of others' in the view of service to human is service to god. But physical organs, beauty, 64 kalas are based on punya & pap earned by oneself through the life cycles. Afaik there are no references of such donations in Hindu mythology! After one's death, the ash of vital organs would be collected and is poured into holy rivers which will liberate soul from pap(salvation) & give them better life or mukthi(liberation). If the organs are donated, the ash from such parts can't be collected.
king Shibi donated his organs to save life of a pigeon from an eagle as kshatra dharma!
