Once, there was a guest who spent Shabbat in the home of Reb Hillel of Paritch. When the cholent arrived, the guest declined to take, saying that the doctors had forbade him from the repast.[1]
“Take,” said Reb Hillel, “I take responsibility.”
Indeed, the guest took a plate of cholent. However, when he reached to take a second serving, Reb Hillel said, “This second bowl is on your own shoulders.”
There is a difference between eating cholent as a mitzvah of enjoying the Shabbat and eating the cholent for mere corporeal pleasure.
