Yoga can mean many things, but its original meaning is ‘union’ and refers to the loss of our illusory sense of a separation or self. Most of us experience ourselves as a separate being that must compete with other beings for love, resources, and money to achieve happiness. This sense of being a separate self is the root-cause of all suffering according to Yoga and is caused by what Yoga calls Avidya (illusion). Yoga helps us see through the illusion of separation so we can experience the truth of unity and wholeness that is our birthright.
