This is one of the most common meditations, we living in stressful times and we need to practice this at least 3 times a week.
Now just remember to read tips on meditation and chakras 101
what we need:
music from YouTube
crystal: Amethyst or clear quartz
incense or oil: lavender or sandalwood
this is totally optional: lavender lotion on my arms and neck, the aroma helps to relax.
pick your favorite position and concentrate in your crystal for at least 1 minute then close your eyes and visualize it in your mind. You can leave the crystal in your hand or if lying down place it in your forehead and breath while listening to the music.
My experience : I laydown in my bed very comfy, my crystal in my palm , breathing slowly, at sometime my mind was filled with clutter thoughts but I fight back and regain a clear state. After a while I began to feel like floating and felt super relax.
