The work you are doing with me has stood the test of time, 8,000 years in fact, and is therefore beyond debate. What takes effort is application and this is why the daily sounding board is the core instrument, rather than knowledge or intellect, for personal change.
You can be challenged by boss, client, self or husband, wife or me to align your heart with nature and therefore walk the path of your life. I'd suggest the cheapest and best option is me.
