On International Yoga Day, the differently abled show there is no limit to what they can achieve. Gulshan, a different abled man, demonstrates terrific yoga skills on a wheelchair. He says yoga helps in keeping fit. Gulshan and his other differently abled friends started doing yoga right from their school days, he says. It's been 15 years that they have been doing yoga. They even performed an improvised version of "surya namaskar" by joining together two wheelchairs.
