I believe that donating body to science is a good thing when the students study on already dead body.

But I have a question about donating organs to keep living.
Whilst our physical bodies are just means for us to be on a physical plane - we don't look back at them when they die and we no longer need them.

But when that body is still alive - our astral body is attached to it and that attachment is strong and protected.

So say a donor died and his heart for example lives in another person. Would that not interfere with further tasks of the donor for the attachment to the alive part is still there? And would that also not interfere in spiritual level with a person whose physical body was saved by donation?
