The AriZal, Rabbi Yiztchak Luria, zt"l, explains that on the night of Pesach it was vital that the Jews be on a level of Mochin de'Gadlut, expanded consciousness. This is because they were lacking in holiness and steeped in impurities, and otherwise never have been able to leave Egypt.
The Jews of Egypt were therefore given Awareness, and not in the gradual progressive manner in which expanded consciousness is normally acquired. Their levels of consciousness came to them in an inverted manner: Mochin de'gadlut prior to Mochin de'katnut, the level of constricted consciousness. However, the the very next day, the day after the Exodus, they were back to "normal", receiving the Katnut and having to progressively achieve the Gadlut.
It is possible for us to receive Mochin, this consciousness or wisdom, every single day. A person begins his day attempting to serve Hashem and, as the day wears on, he himself progresses; reaching ever greater understanding in serving Hashem. Every single day we must try to draw this wisdom upon us. It is the wisdom to recognize and understand Hashem, come close to Him and devote ourselves to serving Him. Just as no two days of our lives are exactly the same, the chochmah of the day is never the same. The chochmah of today is never the same as it was yesterday or tomorrow. Each new day provides us with a different set of concepts and experiences which make up that day's chochmah; the wisdom we are to use in order to know and come closer to Him today!
The essence of the day is light, spiritual light (so to speak). Each day, we have to try to attain this light. How? By extracting the good that is inherent in today, in every single day. The day, however, starts with night. It begins with darkness, the barriers that prevent us from reaching our goal. We have to always strengthen ourselves and make every possible attempt to break through the obstructions and obstacles surrounding us on that day. Only by discovering the good in every single day and utilizing the knowledge that Hashem is in control of everything that happens, THAT HE IS KING, only then can we recognize and draw closer to HIM.
During the Sefiras HaOmer, as we count, we should grow and realize that this is an evolution from the matrix of this world to the truth of the next.
