Body and Brain Yoga and Tai Chi is hosting a Mindfulness Walk to raise money for the Earth Citizens Organization (ECO) from 11 a.m. to 2 p.m., June 18, at Menotomy Park, in Arlington. Organizers say the event allows people from the Boston area to come together and raise awareness about mindfulness and ways that individuals can create a healthier, happier, more peaceful world.

“Mindfulness practices can help you to sleep better, relax your mind and manage stress and make better decisions,” says event coordinator Danielle Swanson. “The ultimate goal here is to raise awareness and have some fun.” Mini yoga and tai chi classes will also be offered at the walk, along with games and activities for the whole family.

ECO is a nonprofit organization dedicated to developing leaders that create healthier communities for a more sustainable world. ECO leaders teach outreach classes, create community projects and help people create positive, lasting changes in their lifestyles.

Cost: Free, with donations accepted. Location: Menotomy Park, 150 Jason St., Arlington. For more information, call 781-707- 6420 or visit EarthCitizens.org.
