At first glance, it seems that the Exodus from Egypt is not nearly as important as the giving of the Torah.
The Exodus is the mere deliverance of the people of Israel from slavery, whereas the giving of the Torah is the event that shaped the character of our people.
In other words, the giving of the Torah is the beginning of Jewish history, whereas the Exodus from Egypt—like the stories about the patriarchs—is, in this sense, prehistory.
If we translate historical events into terms pertaining to each individual's pilgrimage toward his true goal in life—the Promised Land—then the three festivals, together with their natural/agricultural symbolism of spring (Passover), reaping (Shavuot), and harvest (Sukkot), can be seen as landmarks along that path.
The individual journey begins when a person tears himself away from the state of aimlessness.
This is the first step.
At this point everything is still in the embryonic stage, incomplete and undefined—the festival of spring.
Clearly, at this stage one does not fully understand the significance and future consequences of the spontaneous first step into the unknown.
Only later does one reach a degree of maturity and self-knowledge that gives an understanding of the road taken.
This is the time of the receiving of Torah, the feast of reaping.
And only long after, possibly many years later, does one reach full awareness and the ability to enjoy the good fruits.
This is the tranquil hour of "the season of our joy"—the feast of harvest.
These three stages of spiritual development can be found, in various forms, in the life of every individual, as well as in the spiritual and historical course of the nation as a whole.
The Exodus from Egypt is the departure from material and spiritual nothingness in the direction of a new and as yet unknown destination.
The spiritual baggage at the moment of this crucial decision is almost nonexistent.
At most, it is "the bread of affliction."
Only later, farther along the path chosen without knowledge, does one reach full understanding; only then are goals and aspirations formulated in fixed laws.
Then a person can see things in their entirety and evolve a bird's-eye view of his way in life and what it entails.
This is the hour of the giving of Torah to the entire nation, and the hour of the receiving of Torah by the individual.
The time of receiving the Torah is a time of turmoil and inner strife, despite the newly acquired spiritual and intellectual maturity.
Things are forced upon us—"God forced the Mount [of Sinai] over the people of Israel like a pail" (Shabbat 88a)—and we find it difficult to absorb all of this novelty, which, however close to the heart, is as yet foreign to the spirit.
Only after a lengthy period of digestion and adjustment does one attain a sense of inner integrity, wholeness, and peace.
It is then that one feels capable of harvesting the crops that have grown in the course of time, and of enjoying them in calm and happiness.
There are three points, then, in a man's path: the decision, the understanding, and the rejoicing.
All are essential and important, but not equally important.
Which one bears the greatest significance?
At the point of departure, the people of Israel were a nation of slaves in body, mind, and spirit.
They had no spiritual content or any real goal in life.
The only thing they did have was a vague sense of continuity, an obscure link with their forefathers.
This is what prevented them from assimilating completely with the Egyptians, and what prepared them for what they were about to be given.
Then came the call to depart from Egypt.
The very desire for freedom was a tremendous revolution in the soul of this nation of slaves.
It was the awakening of the need for inner freedom that exists in the soul of every individual.
And although they did not yet know God, and had no idea as to how the Exodus would in fact occur—they believed.
The slaves had neither knowledge nor understanding, and yet they went out into an unknown and unmapped desert.
Such a spark of faith can enable those who possess it to overcome all dangers and obstacles.
True, this path of faith is almost bereft of profound intellectual content, but it creates a link that goes much deeper than that of any other kind.
It is a relationship of devotion, of inner oneness beyond perception, with the Divine.
This lightning decision, this inexplicable faith, conceals within itself the seeds of all that will in due course be revealed.
This is where the relationship begins and where its character is shaped.
The overt, external revelation occurs at a later stage.
But the inner, essential relationship is there from the very beginning, from the very first act of faith.
This is why the people of Israel were able to say, prior to the giving of Torah, "We shall do and we shall hearken" (Exodus 24:7), because their essential link with the Torah, albeit hidden, was there from the first.
