There is a small amethyst geode beside my bed. When I've had a stressful day, I visualize that it cradles me like a fetus in my mother's womb . The healing I feel from this is gently calm and peaceful.
I carry the amethyst womb image with me, and use it throughout the day when it is stressful and feel overwhelmed.
I love crystals and use them more and more in my spiritual walk.
In the Native American tradition, I carry a small pouch with several crystals in my purse. I recently attended a class on setting up crystal grids for various intentions.
When I travel, I am always drawn to crystals and rocks cut in the shape of a heart. I am looking at one right now made of red jasper. I use it to ground myself. I hold the small red jasper heart, and I feel connected to Mother Earth and to all that is.
