Before continuing, make yourself rooted.
Slow down, breathe deeply, and focus on your feet. Feel the sensations on the soles of your feet; it could be a faint tingle, or an itch, or the pulse of blood flowing through. Extend your sensitivity to the hardness of the floor, and drop deeper through the many layers of wood or stone or air that separate your feet from the earth. If you feel inclined to root yourself further, feel into the bedrock, the crust, the mantle, the molten iron core of the earth. The rest of this essay will be here when you're satisfied with grounding.
