Why can rites for karmic creditors be conducted again? Does that mean the previous rite was not done properly?

It does not necessarily mean that the previous rite was not done properly. There are two ways to understand conducting further rites to help karmic creditors move on. One is that, because we once had a connection with them, we continue to help when we have the means to do so. The other is that we regularly build up resources of merit beforehand. Whenever someone participates again, we do not have to focus solely on whether the previous rite was effective.

It is like donating to a charitable cause: having helped once does not mean we cannot help again. Even if an earlier debt has been repaid and we have wished the other party well in moving to a better place, we can still offer further help if they need it and we have the ability. Because that connection once existed, being willing to continue dedicating merit to them expresses compassion, joy in helping and generosity. We do not have to keep calculating how much we still owe or wondering whether they have come to collect another debt.

In our religious understanding, there may be more than one karmic creditor connected with this life and our past lives. Having addressed one connection does not mean there are no others that we do not yet know about or that have not yet come to light. Regularly building up these resources is like saving money beforehand. When a matter later needs to be addressed, we already have some blessings available, giving us better conditions for working toward a resolution.

All of this depends on having the spare capacity and keeping within our means. If we can afford to offer more help, that is a good thing for unseen beings and also allows us to accumulate merit and blessings. This explains the meaning of doing more. It does not mean that, whenever someone participates a second time, we can conclude that the first rite must have been done poorly.
