What is it to send ghosts to the temple after death?

People belong to a bardo (similar to the soul of the world) within 49 days after death. At this time, good and evil are undecided, and turning over a dead person can become good.

If the family doesn't cross over and the gods (souls) wander, at this time, if they are listed in the temple, they will have a foothold, and they can go to the temple to listen to the scriptures and smell the dharma, and they can be reincarnated if their merits are satisfactory.

Go to the temple and put up a sign for the dead.
