RIO DE JANEIRO (AP) — Dozens of Brazilian yoga aficionados saluted the sun in unison in a Rio de Janeiro favela for the inaugural class of a free course allowing residents of the low-income community to qualify as yoga teachers. Krishna Das, a renowned American vocalist born Jeffrey Kagel and known for his performances of Hindu devotional music known as kirtan, led a spiritual practice and attendees prayed, sang, clapped and even danced. “I felt like I was in another world,” Luciene Costa Gonzaga de Andrade said at the event Wednesday.
