Bereshit B: Chapter 56
"And the children of Yisrael stripped themselves of their ornaments from Mount Horeb"

The Revelation of Light on Mount Sinai was so great that it extinguished all darkness, including death. When the Israelites sinned by building the Golden Calf, they mirrored Adam's original sin and disconnected from the Light. Death was reborn. Reading this section helps replenish the original quantity of Light that existed on Sinai, and arouses the forces of immortality.
