Daf Yomi - Beitzah 10 - True Simchas Yom Tov

The Gemara states that if one does not chose the doves prior to Yom Tov, there will be times that he will come to take doves on Yom Tov and all the doves will be lean, and he will not take any of the doves. This decision will result in one not being able to partake in the joy of the Yom Tov. It is worth contemplating the fact that HaShem gave us the mitzvah of being joyous on Yom Tov, yet He left it in our hands to determine what is deemed to be Simchas Yom Tov, joy of Yom Tov, and what is not deemed to be Simchas Yom Tov. Even having to eat lean doves on Yom Tov can be considered a lack in the mitzvah. Thus, not only do we have to praise HaShem for giving us the Yom Tov, but we thank HaShem for allowing us to ascertain what is considered true Simchas Yom Tov.
