Perhaps these two descriptions of the nature of the etrog can help us better understand another midrash, this one found in Parshat Emor. In this midrash, our sages compare the four species to four different types of Jews. The etrog, which is both fragrant and tasty, represents the complete tzaddik.  It is possible that the aforementioned qualities of the etrog can also fit in with the symbolism of viewing the etrog as the tzaddik. The requirement of a similar taste for the bark and fruit teaches that a true tzaddik is pious both internally and externally. He serves Hashem with the best intentions and his actions match his inner thoughts. This genuineness naturally produces the second trait, consistency. One who is truly righteous will serve Hashem under all circumstances without condition.  Just like the etrog remains on the branch all year round, Torah observance for a tzaddik is not a matter of convenience, but a lifelong commitment.

 

This lesson can also be understood through the connection between the Yamim Noraim and Sukkot. Sukkot finds itself at the end of of the "Tishrei" holidays. After we are judged by Hashem on Rosh Hashana and Yom Kippur, we bask in the glory of G-d by sitting in the Sukkah. Throughout our liturgy, Sukkot is described as "z'man simchateinu"- "our time of joy."  Even though there is an obligation of simcha on every holiday, the Torah places a particular emphasis on simcha in the context of Sukkot.  In essence, we transition from days of awe to days of joy. Perhaps the Torah teaches us an important lesson with the juxtaposition of these two themes. It may seem like Yom Kippur, with all of its prohibitions, prayer, and solemnity, might hold more weight than the more cheerful chagim that follow. However, by emphasizing joy on Sukkot, the Torah is reminding us that joy is just as crucial to our service of G-d as repentance is.  After Yom Kippur, we all feel like "etrog Jews." We have spent twenty five hours in shul, refreshing our bodies and souls, striving to reach the spiritual heights of the tzaddikim among us. And yet, it is all too easy for this inspiration to fade. G-d understands this, and therefore encourages us not to let the great spirituality we've worked for disappear, but instead to channel it into a new, and equally important form- simcha. Just like the etrog is consistent in its mission, so too must we be consistent and not only serve Hashem out of awe and fear, but out of joy as well. 

  

May this be a year of blessing and joy for all of us, and may we continue to find joy in all aspects of our service of Hashem.
