There had been reports that the government at the Centre was planning to celebrate World Yoga Day - that falls on June 21 - with great fanfare. Now, it has emerged that Prime Minister Narendra Modi is preparing for what is billed to be the world's largest mass yoga demonstration, to be held along a stretch of Rajpath - from Rafi Marg to India Gate. Reports suggest the Union Ministry of Ayurveda, Yoga, Naturopathy, Unani and Siddha (Ayush) has requested some government departments to join the prime minister for a 33-minute yoga session on that day.
