Sage Kapila explains the Yama Logam activities to Mother Devahuti. Hell Servants are Punishing the Wicked Sinners Cruelly such as Body ripped by Two Elephants, Hands and Heads Cut off and made to run for a Marathan Race, Vultures & Dogs Eating their own flesh Slowly to be seen by them, Cooked in the Hot Oil, Beaten with a sharp tinSheets .., Crushed Alive by Python(Anakonda)..., Pushed from a Mountain Cliff & so on. This is not done to punish them. This is meant to purify the soul (Clean the soul.) Just like Washing Powder
