The same is true for all phenomena in the world their future existence is a reflection of the elements contained, albeit infinitely compressed, in their beginnings. The initial moment of existence of something, when it transitions from non-existence to existence, is the most potent, important moment. Subsequent stages of early development are critical, but not as critical as the first instant. Later stages are even less critical, and so on, each phase a further revelation of the initial coding. Therefore, the moment which demands the greatest care, the greatest intensity and the greatest purity, is the very first moment.
Time is also a creation.
The Jewish year, with its calendar of seasons and holidays, is an organic entity. Since these days are the beginning of our year, the most critical for launching the new year in the right direction, we endeavor with extreme care to try to live correctly from Rosh Hashanah through Yom Kippur. Mistakes made during this phase will be harder to correct later, and efforts made during this phase will reap greater rewards as the year progresses. The way one begins the year will determine how the rest of the year reveals itself. If one can form the genes of the year correctly, the fetus will develop correctly and the child and adult will be wholesome.
