Among the participants will be a firefighter, a comedian, an investment banker, a teacher, an activist and a human rights worker. Some are new to meditation, some have been meditating for years, and of course many fall somewhere in between. Each will be asked to reflect on their experiences—which will no doubt range from pleasant to difficult—and then blog and/or tweet about them. All feedback will be posted on Salzberg’s website. Organizers hope the blogs will inspire others to also take part in the challenge.
