Since then, thousands of people hold yoga programmes across the world on this day.

Addressing a huge gathering at the Ramabai Ambedkar Maidan on the occasion of the third International Yoga Day celebrations in Lucknow, Mr. Modi said, "The traditional practice has now become part of every person’s life."

“Many countries which do not know our language, tradition, or culture, are now connecting to India through Yoga. The practice, which connects body, mind and soul, has played a big role in binding the world too,” he said.

Donning a white T-shirt and loose trousers, Mr. Modi performed asanas along with over 50,000 yoga enthusiasts braving early morning drizzles.

Mr. Modi asserted that attaining “wellness” through yoga was more important than simply being physically fit.

“Just as the importance of salt is not only to lend taste to food, but also ensure well-being of the body, similarly Yoga can have the same importance as salt has in life,” he said.

''Yoga is about health assurance. It is not even expensive to practice. I urge everyone to make yoga a part of their lives,” he said, adding that he was glad to see several yoga institutes take shape over the last three years.
