Hell is a stop on the road to Heaven. The journey to self-actualization goes through hell. If we take it here, it will land us in Heaven before we die. If we take it here then we transform hell itself into heaven. אם יש דין למטה אין דין למעלה
The Zohar, Alter Rebbe, Rebbe Nachman & Rav Kook on lower and higher forms of Teshuva.
