From the New York Times:
The lesson began with the striking of a Tibetan singing bowl to induce mindful awareness.
With the sound of their new school bell, the fifth graders at Piedmont Avenue Elementary School here closed their eyes and focused on their breathing, as they tried to imagine “loving kindness” on the playground.
…
This is what is known as mindfulness training, in which stress-reducing techniques drawn from Buddhist meditation are wedged between reading and spelling tests.
…
Asked their reactions to the sounds of the singing bowl, Yvette Solito, a third grader, wrote that it made her feel “calm, like something on Oprah.” Her classmate Corey Jackson wrote that “it feels like when a bird cracks open its shell.”
