Many a year ago – I ate at a Kosher Chinese restaurant called Moshe Peking in Manhattan. People say after Chinese food one feels hungry. Why? Many theories exist. It is low in protein. It is high in carbohydrates. It’s the salt or MSG. Whatever.
Some pleasures are similar – one has a short pleasure but shortly after they feel lacking. Why? Material pleasures give a person a temporary high. Material things are temporary. We have a high level soul – that is eternal. The Material does not satisfy the spiritual soul.
It is difficult to discern what is a material pleasure – because material pleasures may be mixed with spiritual pleasure. Let’s say you go to a restaurant. Now you are generous and you flip the bill or pay for the group. The eating was material pleasure – but the act of being generous is a spiritual pleasure.
Some don’t discern – so they think that the eating gave them the pleasure – but it was really the kindness you did during the meal that gave you the pleasure.
