Below is part two of the National Geographic programme, 'Light at the End of the World' which explores traditional approaches to meditation, wisdom and enlightenment, especially as developed in Buddhism. Much of the material seem odd to a Western mind. It is worth remembering however that our own culture had, until recently, many similar shamanistic and ritual practices that delved into the nature of the body, mind and existence itself.  As we seemingly grow inexorably towards a technological future where human experience is increasingly divorced from the realities of our bodies, it is interesting to see the flourishing of many Eastern mind-body practises in our societies.
