Consider the following excerpt from Mahabaratha
"Then Shakra, the lord of the deities, endued with blazing prosperity, addressed Yudhishthira and comforting him, said, ‘O Yudhishthira of mighty arms, come, come, O chief of men. These illusions have ended, O puissant one. Success has been attained by thee, O mighty-armed one, and eternal regions (of felicity) have become thine. Thou shouldst not yield to wrath. Listen to these words of mine. Hell, O son, should without doubt be beheld by every king. Of both good and bad there is abundance, O chief of men. He who enjoys first the fruits of his good acts must afterwards endure Hell. He, on the other hand, who first endures Hell, must afterwards enjoy Heaven. He whose sinful acts are many enjoys Heaven first. It is for this, O king, that desirous of doing thee good, I caused thee to be sent for having a view of Hell. Thou hadst, by a pretence, deceived Drona in the matter of his son. Thou hast, in consequence thereof, been shown Hell by an act of deception. After the manner of thyself, Bhima and Arjuna, and Draupadi, have all been shown the place of sinners by an act of deception. Come, O chief of men, all of them have been cleansed of their sins. All those kings who had aided thee and who have been slain in battle, have all attained to Heaven. Come and behold them, O foremost one of Bharata’s race.
Krishna in Geetha says
As a person sheds worn-out garments and wears new ones, likewise, at the time of death, the soul casts off its worn-out body and enters a new one.
From the above two, we can comprehend that hell in Hinduism is temporary. But my doubt is that are there any slokas in Hindu texts mentioning permenant hell? Are there any explicit statements stating either in support or against permanent hell?
