Because yoga has an incredible amount of physical/spiritual/emotional/psychological benefits that should not just be for the privileged, whether it be socially, financially, or physically. Indeed, people who are under-privileged may suffer more than others and need it the most. Yoga is such a human journey of the self, through the self, to the self that everyone needs, no matter one's position in society. I would love to give back to the world what it has given me (i.e. health, freedom, education, relative wealth, peace, love etc...) to those in need.
