The Water borrows the power from the Fire to become the Air, to evaporate. Without power, Fire is hardening into the Earth, cooled down and solidified like slag. Air releases the borrowed power of the Fire back to Earth in the form of Lightning.

In the Hagalaz rune, we saw how lightning conceives crystals deep in the Earth, but what happens to the Air after that?

The Ehwaz rune is a mirror twin of the Hagalaz. The lightning of Hagalaz starts at the level of Air, in dark stormy clouds of the sky, and strikes down through the Horizon to the Earth.

Ehwaz, in turn, also starts as lightning at the Air and goes down, but after reaching the horizon, it beams back to the Air.

In Grímnismál, we read about Bifröst, the rainbow bridge that connects Midgard and Asgard. While all the gods ride on horses across the Bifröst, Thor has to wade through the rivers.

Is it because only the horse is capable of going across the Bifröst? Or it's because in nature, rainbows appear after a storm, so Thor makes Bifröst appear, letting other Æsir ride across? We already saw this rainbow in the Raido rune, ascending from the Emptiness to Air.

Let's do Ehwaz now:

• Left and right forearms serve as vertical axes starting with elbows in the Fire, going along the Earth up to wrists of Emptiness, and ending with fists in the Air.
• Bent fingers of the left palm go down from Air to Emptiness.
• And the tips of fingers of the right palm start at the Emptiness level and return to the right fist of Air.
• Together, both hands form a shape resembling the Ehwaz rune while the space in between reminds you of the silhouette of the horse head, looking at you.

When you do the Ehwaz, you may feel the presence of the spirit of change. Like an old friend reminding you of your forgotten dream and inviting you to the journey. Maybe when we die, the same friend meets us to finally take us back, to that point on the horizon which we were never able to reach.
