Yoga is an ancient form of discipline, uniting the physical, mental and spiritual aspects, and is practised worldwide by those who desire to stay healthy and fit. It is generally believed to have originated from India. In December 2014, the United Nations General Assembly (UN) declared 21 June as International Yoga Day.

The commemorative day was first celebrated the following year, thus marking the beginning of a tradition. The date was suggested by India's current Prime Minister Narendra Modi, as it falls on the Summer Solstice.

During his address to the UN, Modi said: "Yoga is an invaluable gift of India's ancient tradition. It embodies unity of mind and body; thought and action; restraint and fulfilment; harmony between man and nature; a holistic approach to health and well-being. It is not about exercise but to discover the sense of oneness with yourself, the world and the nature."

In celebration of the day, IBTimes UK has compiled a list of top quotes from Yoga loving celebrities.

Finding the balance between the physical and the mental

According to Shruthi Jain, a certified and practicing yoga instructor in Bangalore, India, yoga is about more than just physical fitness, with the asanas just the "tip of the iceberg". Yoga, she says also works on "an emotional level".

Explaining the common misconceptions about yoga, Jain said, "Often yoga is associated with being a fitness practice or asanas. Although yoga does offer many profound benefits to our body's flexibility, strength and balance, it also helps us experience emotional well being and connect to our inner, essential self. At its core, yoga means unity – the union of mind, body and soul.

"The intention of consciousness-based yoga practice is to integrate and balance all the varied layers of our lives so that our body, mind and spirit flow in harmony. Over time, yoga becomes a part of our lives and a part of us, instead of just something we 'practise'".
