Om Namasivaya nama:
Sri Yama dharma raja explains to Savithri that, one who does 100 Aswamedha yagam will become Indran and the achiever of 1000 Aswamedha yagam will become Sri Vishnu. Savithri composed and praised Lord Yamadharma known as Yamashtakam. Savithri asked YD why do people go to Narakam (Hell) based on what Karma. YD explain 86 Naraka Loka exists and where proper treatment is given to the sinner. After death the soul gets a Yadana Sareera to undergo these punishments.
