Hi, in Igerret HaRamban the Ramban quotes Razal (Nedarim 22a) and says:
כל הכועס כל מיני גיהנם שולטין בו
Anyone who gets angry, all kinds of Gehenna rule over him
What does this mean? Isn’t Gehinom a punishment in the next life? How could someone have punishment here in this world control him if he gets angry?
