The word yoga means "union" in Sanskrit, the language of ancient India where yoga originated. We can think of the union occurring between the mind, body and spirit.
What is commonly referred to as "yoga" can be more accurately described by the Sanskrit word asana, which refers to the practice of physical postures or poses.
Asana is only one of the eight "limbs" of yoga, the majority of which are more concerned with mental and spiritual well being than physical activity. In the West, however, the words asana and yoga are often used interchangeably.
Many people think that yoga is just stretchinh. But while stretching is certainly involved, yoga is really about creating balance in the body and calming your mind through developing strength and flexibility of your body. This is done through the performance oc postures, meditation and breathing techniques.
