…The stem yuj, which means to yoke or bind? There are different interpretations of what is binding or connecting. Some yogis consider it to be more about connecting the mind with the body, through the action of breath.
As humans, our brains are constructed in such a way that it is easy to spend too much time in the future or the past. So, in the physical practice of asana, and in meditation, for example, we are practicing connecting our minds to our bodies.
Other yogis consider the practice of yoga to be more about connecting to the divine, or to source, or to your community at large. The notion that we do not operate in a bubble and that all our actions have a ripple effect on those around us.
Me? I consider yoga to be about both (and more!), because, why pick when they both make sense to me!
