Quakers and Mindfulness
To clear your mind and become ‘spiritually focused,’ you have to learn to concentrate what George Fox called “thy wandering mind.” Unfortunately, many Quaker writings don’t specify a way to develop this concentration.
But concentration is a central part of mindfulness, and the literature on mindfulness contains a lot of advice about learning to concentrate. Most of it boils down to repeatedly focusing your attention on your breath or some other aspect of your experience.
