During Rosh HaShanah we exalt the Creator because the very first and most important task of a person is to reveal the Creator and connect with Him.
Therefore, exalting the Creator and revealing Him as the most important force that influences everything that exists is the New Year. All sorts of customs of this holiday stem from its various particular manifestations.
We eat an apple because it represents the apple from the garden of Eden and we dip it in honey to show that we want to correct this sin.
During the New Year we eat fish heads. This means that we want to be the head, not the body, to manage our own correction and at the same time bring goodness, love, and good connection to all parts of the universe.
Question: Can we say that every time I wake up to the Creator I feel the New Year?
Answer: Yes. When a person begins one’s connection with the Creator, this is called the New Year. Moreover, this can happen every day. All Jewish holidays symbolize the spiritual states that a person undergoes.
