Rabbi Haim once ascended to the firmaments to see the difference between the worlds. He first visited Gehenna (Hell).

He saw a vast hall with long tables covered in the most magnificent foods. But the people sitting there were skeletal and wailing in agony. As the Rabbi looked closer, he saw that every person had wooden slats splinted to their arms, stretching from their shoulders to their wrists. Their arms were perfectly straight and stiff; they could pick up a spoon, but they could not bend their elbows to bring the food to their own mouths. They sat in front of a feast, starving in bitterness.

The Rabbi then visited Gan Eden (Heaven). To his surprise, he saw the exact same hall, the same tables, and the same magnificent food. Even more shocking, the people there also had wooden slats splinted to their arms, keeping them from bending their elbows. But here, the hall was filled with laughter and song. The people were well-fed and glowing. As the Rabbi watched, he saw a man fill his spoon and reach across the table, placing the food into the mouth of the man sitting opposite him. That man, in turn, filled his spoon and fed his friend.

The Rabbi returned to Hell and whispered to one of the starving men, "You do not have to starve! Reach across and feed your neighbor, and he will feed you." The man in Hell looked at him with spite and replied, "What? You expect me to feed that fool across from me? I would rather starve than give him the pleasure of a full belly!"
