In meteorology, thunder is the by-product of the movement of lightning through the atmosphere. As lightning snaps through the air, it instantaneously superheats the air around it, causing the air to expand in an explosive fashion, creating a shock wave that sounds like a giant clap.
In the Navajo tradition, Thunder can be a protective force and is considered to be one of the Holy People. In Navajo culture, the Holy People are immortal beings that can take the outer form of landscape elements, animals, plants, and celestial bodies. Conversely, Thunder can be personified as an evil and destructive force, which means that when dealing with such a powerful entity, one must be cautious.
