We often understood this pasuk as an exhortation to serve Hashem with simchah and joy. Yet, the Torah appears to add another criterion: “when everything was abundant.” Why does abundance matter? If one were to ask the average person, “How are you doing?” the response would likely be, “Baruch Hashem, I am blessed. I have what I need. Of course, I could always use more, but I am managing with what I have.” Implicit in this answer, however, lies a subtle deficiency. “I could always use more” often translates into “Something is still missing. I am not fully satisfied. There is room for improvement.”
If this is truly a person’s perspective, genuine joy can never emerge. As long as one focuses on what he lacks, rather than on the countless blessings Hashem has already bestowed upon him, he will remain incapable of experiencing true simchas ha’chaim. Gratitude and contentment are the foundations upon which authentic joy is built. A person who constantly compares himself to others, measuring what they possess against what he does not, condemns himself to a life of frustration and quiet discontent.
To whom was this parshah given? We are being enjoined to serve Hashem meirov kol, from amid complete abundance. Everyone will find something that is missing in his life. Even if he has it all, if his neighbor has more, then he no longer has it all! The Chafetz Chaim posits that the contrast between Yaakov Avinu and Eisav is reflected in the barometer by which each defined personal wealth and satisfaction. Upon encountering Eisav after years of separation, Yaakov presented his brother with an elaborate gift consisting of livestock, precious possessions, and valuables. Eisav, assuming the posture of the magnanimous benefactor, initially declined the offering. “Yeish li rav,” he declared. “I have much.” Yaakov, however, urged him to accept the gift, explaining that he wished to express gratitude and reconciliation. With regard to his material abundance, Yaakov countered, Yeish li kol, “I have everything.”
These two phrases reveal two diametrically opposed perspectives on life. Eisav proclaimed, “I have much.” Indeed, he possessed immense wealth and material abundance. Yet, despite all that he owned, he still felt he was lacking. Whatever he had was never enough. His craving for more could not be satiated, because one who measures life solely through acquisition can never experience true fulfillment.
Yaakov Avinu, on the other hand, possessed far less in material terms. Yet, he declared, Yeish li kol, “I have everything.” Why? Because Yaakov viewed life through the prism of emunah and bitachon. Whatever Hashem granted him was precisely what he needed in order to fulfill his mission in this world. Thus, he lacked nothing, because a person who recognizes that all he possesses is a gift from Hashem no longer measures life by quantity, but by purpose.
How many people postpone “happiness,” while waiting for it all to come together, for life to become “complete” (as they see it)? They never have enough money; they require greater success (according to their flawed perception of success); they need greater recognition and fewer problems. Meanwhile, life passes them by, and the happiness they yearn for eludes them. They always want more, so they can never really achieve true, enduring joy. This is Eisav’s philosophy. His obsession with “more” eventually destroys his ability to appreciate what already exists. He is condemned to living a life of perpetual hunger.
Yaakov Avinu teaches otherwise. Fulfillment begins when a person recognizes that Hashem does not make mistakes. The family one was given, the abilities one possesses, the challenges one endures, and even the limitations one confronts have all been carefully measured by Divine wisdom. This does not mean one should abandon ambition or cease striving for growth. Judaism values effort, aspiration, and accomplishment. A profound difference exists, however, between striving from inner peace and striving from inner emptiness. One may pursue success, while simultaneously recognizing: “If Hashem determines that this is as far as I shall go, then I still possess kol.”
We now understand, explains Horav Yechiel Tzuker, shlita, why the Torah attributes the Tochachah, curses of Sefer Devarim, to a lack of gladness in serving Hashem. Meirov kol is explained by Rashi, “When you had all the good; when you were not in need of anything.” As long as a Jew does not adopt the yeish li kol attitude to life, he indicates that his belief in Hashem is flawed. Why did you not realize that you had it all? Why was it never enough?
True blessing begins not when one acquires everything he wants, but when he understands that what Hashem has given him is already everything he needs.
