Pacing back and forth inside one’s house gives one the power to revive the dead.

This is as it is written concerning Elisha when he resurrected the Shunamite woman’s son. It is written of him: “he walked… once this way and once that way” (2 Kings 4:35) .

In the Tikkunim it is brought: “If not for the lobes of the lungs fanning the heart, the heart would consume the entire body” (Tikkuney Zohar #13, p. 28a). The lungs and the heart are the aspects of Yaakov and Yosef.

For Yaakov corresponds to truth, as it is written, “Give truth to Yaakov” (Micah 7:20), and truth is synonymous with Torah, as it is written, “The Torah of truth” (Malachi 2:6). And the Torah comprises Five Books, paralleling the five lobes of the lungs (Tikkuney Zohar #25, p.70a) .

Yosef corresponds to the heart, for Yosef was called “TZaPhNaT-Paaneach” (Genesis 41:45), and it is written, “In my heart TZaPhaNTi (I have hidden away) [Your word]” (Psalms 119:11) .

Thus when the fire in the heart burns, it can consume the entire body. But in the process of the five lobes of the lungs moving back and forth, they fan the heart and cool down its heat.

This is the reason it is taught concerning Yaakov (Rashi on Genesis 37:2): “Yaakov sought”—namely, the lungs—“to dwell in tranquility, but he was immediately beset by the trouble regarding Yosef”—namely, the heat of the heart.

We see from this that by walking back and forth, even inside one’s house, a person—who is the aspect of Torah, as it is written, “This is the Torah: a man!” (Numbers 19:14)—has the power to cool down the fire, which corresponds to harsh judgments. Thus he can revive the dead, bringing them back to life.
