Go Back to Meron
Refuah
A Yerushalmi once came crying to Rav Dovid Tzvi about the dire situation of his sick son. "Go to the holy site of Meron and achieve your salvation at the tziyun of Rebbi Shimon bar Yochai," the Rebbe instructed him.
"But I have already been to Meron." protested the Yerushalmi.
"Go back." he replied. "Do you mean to tell me that if someone visited a doctor once and isn't yet healed, he shouldn't go back to the doctor again?" The Yerushalmi returned to Meron, and his son was healed.
