"People who spend a great deal of time in their gardens attest to the natural mindfulness that gardening requires. What could be more naturally mindful than weeding? It requires a great deal of sustained attention. Weeds need to be taken up with care: Pull too hard, and the weed breaks in your fingers, leaving the root to grow and spread. Different weeds need different techniques and, sometimes, tools. When we weed our gardens, we have to pay attention to where and how we walk and bend. Move too far in one direction or another, and we'll squash growing things."
