According to CNN, inmates at prisons in Mexico are being taught Kundalini Yoga as a form of rehabilitation. These teachers (as you can see in the video linked below) were once students of the teachings of SSS Harbhajan Singh Khalsa (also known as Yogi Bhajan) . It is the Sikh way of not only serving the people one knows, but serving those in need.
This sort of effort- teaching Kundalini Yoga, meditation and spirituality- are the practices Yogi Bhajan teaches. He strived to create teachers, so that we could be of service to humanity and be “Healthy, Happy and Holy”, which, according to his teachings, is everyone’s birthright.
