Ajahn Dhammasiha recommends to use 'Not Sure', 'Not Certain', 'Anicca' like a broom to sweep away all thoughts and worries and distractions in our meditation.We use the breath as anchor for our awareness, and stay with it. But all thoughts and plans for past and future, all fantasies and images, all worries and concerns we immediately counter with 'not sure', so that they can't take hold of our mind, that we can see them like clouds moving through the sky which we don't own and can't control, and we simply let go. www.dhammagiri.netwww.facebook.com/dhammagiri-forest-hermitagewww.youtube.com/channel/UCJINt0JJBfFm_x0FZcU9QJwwww.tinyletter.com/dhammagiri/archive.
