"The laws of kashrut are very deep; deepest of all is that they are G-d's instructions for life. Nothing can be more profound than for a person to be aware that what he or she is doing is an expression of the will of the Source of all existence. Every time we eat (and that's quite frequently), the laws of kosher give us an opportunity to notice that at the heart of everything in Jewish life is nothing less than the privilege to connect our own will with the will of the Divine. Kosher allows us to consider the enormous potential we have to bring G-d into our lives not only in moments of great spiritual inspiration, but into the day-to-day practicalities of life, into our homes, and into our world."
The laws of kosher are called Chukim, decrees from G-d which we do not understand. Keeping G-d's commands because "He said so" demonstrates and reinforces awe of Heaven. Through the observance of His commandments, we come closer to Him.
Eating may seem like a very mundane activity, but Rabbi Apisdorf reminded me of the potential for spiritual greatness in my kosher kitchen. Keeping kosher helps to define me, because together with keeping Shabbos, keeping kosher transforms the life of Jewish person into a deeply Jewish life.
