Let us bring some examples of this concept. In the chapter, Eternal Life and Temporal Life, we explained the Gemara [Talmud] (Pesachim 68b) about Rav Sheshess, who would review his studies monthly and exclaim, “Rejoice, my soul — for you I have learned.”
The Gemara is puzzled by his expression, for Torah study is vastly more important than the Rav’s own benefit; “If not for the Torah, the entire world would not exist?” The Gemara answers with an important lesson: at first, one studies for his own benefit, and only later can hope to achieve the lofty level of acting purely for the sake of Heaven.
In order to start on the road to perfection, we have to convince ourselves to do good for self-serving reasons. Learn Torah so that you will enjoy it! So that you will refine your soul! Speak to yourself in the language easiest to accept – you will gain from this.
But keep in mind the final goal, of serving Hashem for only His gain, and with time, you can achieve it. We can assume Rav Sheshess learned Torah with a very high level of purity, and he revealed to us the tactic to reach it.
Thus, by focusing on the ultimate goal of Torah study for its own sake, the initial stages of selfish motives become a part of the higher objective.
Another place we find this idea is by Akeidas Yitzchak [the Binding of Isaac]. Avraham Avinu is regarded as the paradigm of chessed [kindness], doing kindnesses to others, and then Hashem tells him to slaughter his own son! How can we understand how this act fit into Avraham’s profound sense of chessed?
The essence of chessed is fulfilling Hashem’s will, and this is what Hashem wanted to test with this command. Was Avraham simply following humanitarian urges to help others, or was it coming from his fear of Heaven? By acting in a way that was the opposite of kindness — killing his child because that is Hashem’s will – he proved that all his lifetime’s efforts were indeed inspired by holy intentions. Only with years of striving towards that goal behind him was Avraham Avinu [Our Forefather Abraham] capable of such a feat.
This could be the intention of the angel’s praise to Avraham after the Akeida [Binding of Isaac], “Now I know that you fear Hashem;” meaning now we know his chessed is not instinctive, but fueled by his fear of Hashem.
So too did Yaakov Avinu excel in the trait of emess, but the emess was fueled by the yearning to do Hashem’s will, not an independent interest to be truthful. And this came to the fore in his interaction with Lavan, when he removed his feelings from his heart in order to serve Hashem in the correct way. This is the epitome of Yaakov’s midda of emess, the central ambition in his life.
In summary, we have two ways to understand Yaakov Avinu’s surprising displays of love towards Lavan. Either he decided that it was the correct thing to do, so he pretended to ignore his negative feelings; or his well-honed emess actually changed his feelings, and he felt the way he acted.
