I recently told how researchers have documented beneficial changes in brain chemistry and function that follow a quiet walk in nature (see Do Yourself a Favor, July 26). With the return of warm weather (and more likely to follow in August), you might have some cool walks planned for your mornings or evenings.

It turns out that walking with awareness is one of the forms of meditation that the Buddha recommended to his followers over 2,000 years ago. Here is a modern commentary on this practice, followed by simple instructions for “walking meditation,” courtesy of Thich Nhat Hanh, a Vietnamese Buddhist priest, meditation teacher, peace activist, and author: Thich Nhat Hanh on Walking Meditation (Lion’s Roar, March 20, 2015)
