What are the sutric references for the dead "seeing" or experiencing prayers/rituals for them? For example, did Maudgalyāyana's mother see him performing prayers for her in the suttas? There is an example in the suttas of a religious leader who has gone to one of the hells and interacts with an arhat and asks him to tell his former students that their path is wrong (I'll have to look this one up). I think the former religious leader can see his student's performing rituals on his behalf too but I'll check. There is also the offering mentioned by Shakyamuni Buddha that can be performed for former relatives reborn in the Hungry Ghost realm but it is not stated that they can actually see the offering although they can receive the merit.
Thanks!
