The Jerusalem Talmud taught that the evil impulse (, "yetzer hara") craves only what is forbidden. The Jerusalem Talmud illustrated this by relating that on the Day of Atonement, Rabbi Mana went to visit Rabbi Haggai, who was feeling weak. Rabbi Haggai told Rabbi Mana that he was thirsty. Rabbi Mana told Rabbi Haggai to go drink something. Rabbi Mana left and after a while came back. Rabbi Mana asked Rabbi Haggai what happened to his thirst. Rabbi Haggai replied that when Rabbi Mana told him that he could drink, his thirst went away.
