Garuda Purana describes the Yama-Loka and the activities of Lord Yama. It tells how the soul takes innumerable births after death, and based on our karmic deeds, we would get salvation or otherwise we would suffer in the hell. In this Purana, the punishments given by Lord Yama for the sins committed by us during our life time is mentioned. It gives a detailed explanation about the ceremonies to be performed after our death, and mentions about the various types of hells situated in the Yama Loka.
