Question: So, is it useful to pray for the deceased and also try to help the deceased with the means that are mastered by Buddhists, who practice Bardho yoga?

Answer: Yes, this is beneficial. But not for the deceased, since he or she have predetermined his/her destiny and by no means we can influence it.

But certainly it is beneficial for those who are trying to help. Through this they perfect their love, as well as power — if they make meditative efforts in “leading” the disincarnated one.
