The Sand Mandala Practice
Find a patch of wet sand just above the tide line, where waves will reach in 30-40 minutes. You may need to check tide charts.
With your hands, a stick, or small shells for ornament, begin making a pattern. Spiral, mandala, concentric circles, abstract. Whatever comes. Don't plan it in advance.
Work without an end goal. The process is the practice. If you want to finish, you don't have to — the tide will either way.
Continue until the first wave reaches your work. Watch it go.
Sit with what you feel. There's no 'correct' feeling — relief, grief, joy, all are honest.
The sand mandala practice makes physical what meditation makes mental: the teaching that nothing lasts, and that knowing nothing lasts is precisely what makes things beautiful while they do. You only need to do this practice once to understand it. You'll want to do it again.
