If one chants the holy name of Hari and then dies because of an accidental misfortune, such as falling from the top of a house, slipping and suffering broken bones while traveling on the road, being bitten by a serpent, being afflicted with pain and high fever, or being injured by a weapon, one is immediately absolved from having to enter hellish life, even though he is sinful.
