As a small child, Reb Zalman Aharon (the "Raza"), the older brother of Rebbe Sholom DovBer of Lubavitch (the "Rashab"), was bothered by the fact that he was noticeably shorter than his younger brother.

One day, the Raza sneaked up behind his brother and pushed him into a shallow ditch. As the Rashab stood up in surprise at the bottom of the ditch, the Raza seized the moment and pointed out that now he was taller.

Rabbi Shmuel of Lubavitch, the father of the two boys, observed the entire episode. The Rebbe asked for a chair, ordered the Raza to stand on it, and asked him, "Tell me, who’s taller now?"

The Raza answered excitedly that yet again he was the taller.

"Aha!" said Rabbi Shmuel. "There you are! To be bigger than your friend, there is no need to pull him down. Simply elevate yourself!”
