Taste the Tree Like the Fruit- Sukkot as a Microcosm of Eretz Yisrael
Rav Kook points out that just as most of the tree is roots, trunk, branches and leaves, despite the fact that the goal is the fruit, similarly most of life is preparations (e.g. eating, dress, work, cooking, raising children), and often one doesn't even achieve his goal. Does that mean that he wasted his life?! The basic question is, if most of life is "tree", and I want to have meaning in life, I have no choice but to find a way to have "taste" in the tree, not just in the fruit. This was the original plan in Eden, and is meant to be the ideal lifestyle, as expressed in the Etrog where the tree tastes like her fruit. Eretz Yisrael is likened to Sukkot, where even the secular/mundane/"tree" has meaning/taste/holiness, and it's all a mitzva.
