Your ability to talk yourself out of any situation knows no bounds. (Just ask the chief of police.) Keeping your piehole shut, however, is a whole different story. Practice the lost art of silence in Juju Spa’s meditation classes, held tonight and every Monday in the organically minded, ecofriendly space. Drop in to the 90-minute class taught by Caroline Peterson, a therapist trained in vipassana meditation. She’ll start by leading a discussion about specific issues and stressors, then guide you through thoughtful breathing and relaxation. She finishes with a talk on managing day-to-day problems by bringing this practice to every aspect of your life. A message you’ll be happy to receive loud and clear. Classes held Mondays, 6 p.m., at Juju Spa & Organics, 728 South Fourth Street (215-922-3235 or jujusalon.com).
