Not every teacher needs an hour. Andrew Weil MD works here in a far smaller window, and the constraint is the point: a short guided introduction that fits into the time it takes a kettle to boil twice.
The territory covered straddles four of our shelves, health, personal development, spirituality and even business, which is a neat illustration of how thoroughly meditation has crossed over from private practice to general life skill. Writing of this kind succeeds by being unembarrassed and unmystical: plain instruction, delivered calmly, with no requirement that the listener sign up to anything larger.
