"Best wishes to everyone on 'International Yoga Day'. Yoga is the medium to concentrate the body, mind and soul, which not only makes the body healthy but also the brain. This is an invaluable heritage given by India to the world, which Narendra Modi ji has worked to take to the whole world. With the efforts of Modi ji, today 'Yoga' has become a lifestyle of people all over the world," Union Home Minister Amit Shah tweeted.
