"Along that path so disagreeable with the stench of corpses and awful with other incidents, the righteous-souled king proceeded, filled with diverse thoughts. He beheld a river full of boiling water and, therefore, difficult to cross, as also a forest of trees whose leaves were sharp swords and razors. There were plains full of fine white sand exceedingly heated, and rocks and stones made of iron. There were many jars of iron all around, with boiling oil in them. Many a Kuta-salmalika was there, with sharp thorns and, therefore, exceedingly painful to the touch. The son of Kunti beheld also the tortures inflicted upon sinful men.
