The word yoga is an ancient Sanskrit word that means union. It is often thought of as union between the body, mind and spirit. In the West, the word yoga is also used to describe a practice in which asanas or physical postures are used to help create balance in the body. It is a great way to develop strength and flexibility, while improving health and wellbeing. In addition, it cultivates the ability to tune into and live in the present moment, encouraging a stress-free state of mind.
