After death, in the coffin, can't the soul go there? is it

The funeral of the ancients generally has two functions: one is to believe that the dead can be resurrected one day, and the other is to expect the dead to enter another world as soon as possible (reborn or enter heaven). So it depends on your expectations. If you expect an old friend to come back to life, then his soul should stay in the coffin! If you expect him to rest in peace as soon as possible and enter another world, then his soul should be gone! Now the explanation of the soul is that it is a brain wave, so lead can block or block it.
