The practice begins with a quick body scan to help you relax, and then I will guide you through the process of pausing to witness your thought, see them as an object, and place them into a burning fire - where they can be reincarnated into life-giving warmth.
Thoughts arise, as is their nature. This meditation gives you a safe space to allow them to rise to your consciousness, acknowledge them, and let them go.
Some experience with mindfulness/catching your thoughts might be useful.
