By observing the precept of "sending from the nest" (to the mother) - shiluaj hakan - which appears in our parashah, the Torah assigns a great reward: "So that it may go well with you and that you may live long" (Deuteronomy 22:7). The precept itself consists simply of driving the mother hen away from her chicks. It is easy to fulfill. Given this, why is such a great reward given for it? Rashi explains that this is precisely what the Torah teaches us: if for a simple mitzvah, which does not generate monetary losses, the Torah promises good things and a long life, how much greater will be the reward for important mitzvot!
In other words, the Torah chose to highlight the great reward precisely in a very simple mitzvah, which does not involve monetary loss, to give us an idea of the extraordinary reward that awaits those who observe the rest of the precepts, and especially the serious precepts, which also cause economic cost.
But this explanation requires further clarification: if the Torah specifically sought "a simple mitzvah," it could have chosen much easier mitzvot, some of which require no action at all to fulfill, such as reading the Shema, which consists solely of reading a text.
What distinguishes the commandment to "send the chicks from the nest" (the mother) and makes it "easy" is the fact that it is not linked to any difficulty. This mitzvah is fulfilled in a situation where the person is not preoccupied with any particular matter, but simply wishes to take the chicks or eggs from the nest, and the only condition the Torah requires is to drive the mother away—a seemingly insignificant act. Regarding this, the Torah states that the reward is great.
In other precepts, such as reading the Shema, Difficulties may arise. For example, when a person is busy and engaged in other matters, and must leave them to fulfill the mitzvah—it requires a certain spiritual strength to interrupt one's own affairs and read the Shema. If the Torah had chosen this Mitzvah to teach us the immensity of the reward for those who fulfill the precepts, we would have thought that the reward is due to the fact that fulfilling this Mitzvah sometimes involves dealing with difficulties.
That is why the Torah specifically chose the commandment to "send from the nest," a commandment easy in every sense: it is an insignificant action, involves no difficulties, and causes no loss. And regarding such an easy mitzvah it is written: "That it may go well with you and that you may prolong your days." How much more so with the rest of the commandments!
Following the commandment to "send from the nest" is written: "When you build a new house, you shall put a fence around your roof." Then the laws for vineyards and fields, the mixing of linen and wool in clothing, etc., are detailed. Rashi comments on this: "If you have fulfilled the commandment to 'send from the nest,' you will eventually build a house and fulfill the commandment of the fence, since one commandment leads to another, and you will attain fine clothing, a field, and beautiful garments.""
From this we see not only the dimension of the reward for an "easy mitzvah", but also the power that an "easy mitzvah" possesses to draw in additional mitzvot.
When the essence of the Jewish soul awakens, even if at first it finds its expression in an "easy mitzvah," this then leads to the fulfillment of other precepts, through which we become worthy of being inscribed and sealed for good, for a good and sweet year in all its details.
