"Progress in Yoga is not necessarily characterized by daily mind-bending revelations.  Instead the path is marked by small but significant changes in how we act and react.  Perhaps we will be more patient when cut off in traffic.  Or we may find ourselves a little less fearful or anxious when speaking in public.  Attraction to violent movies may be replaced with more tranquil diversions.  Sages and saints are born from these beginnings.  There is one infallible sign of growth: We will be more peaceful and happy.  Maybe not everyday in every way, but if our happiness were marked on a chart, the trend over a period of time would definitely be upward."
