Reply To: Yom Kippur like Purim

The mishna in Taanis says כשם כשנכנס אב ממעטין בשמחה as when Av arrives we diminish enjoyment כך משנכנס אדר מרבין בשמחה, similarly onwhen Ador arrives, we increase the enjoyment. What is the connection? Fasting is certainly done lashem shomayim. for the sake of heaven, Hashem but enjoying ourselves through eating might not, so we have Purim where our enjoyment should be lashem shimayim. Yom Kippur when we are not eating misses this enjoyment which should be made up through Erev Yom Kippur.
