Mindfulness is the faculty of not forgetting what to do and what not to do. Alertness is the awareness that knows what is occuring. If mindfulness is lost, you will also lose alertness, and then it is no longer meditation." It is accompanied by a photograph of H. H. the 17th Karmapa's first pilgrimage in India. Sarnath, India.
