Using a body scan, we travel inward to help find certianty in the body. When the world can feel very uncertain and chaotic, we can tune to the body to remind us of what is true and reliable. We can tap into the breath or our heartbeat to remember that there are pieces of life that we can depend on. This type of meditation can be very grounding to the nervous system. Moving the attention around the body can also be a bit easier to maintain focus, especially for beginner meditators.
