The first-ever observance of the International Day of Yoga will be held this Sunday, 21 June.

Yoga originated in India and the word means to join or unite, symbolizing the union of body and consciousness.

Enthusiasts say they see parallels between the work of the United Nations and this physical, mental and spiritual practice.

Dianne Penn sat in on a yoga class at UN Headquarters and filed this report.
