Many people believe that after the death and disintegration of the body, the continuum of the spirit also comes to an end and that the spirit no longer exists, like a candle flame whose wax is burnt. There are even people who contemplate committing suicide in the hope that with their death their problems and sufferings will come to an end, but these views are completely wrong.
