The ‘will’ is what makes you do things. If you want to do things on a regular basis you can achieve it in one of two ways: Habits or Rhythms. The Charlotte Mason approach to training the will is through habits. Habits can become very strong as we often refer to behavior that is hard to break as ‘force of habit’. Charlotte Mason details exactly how to establish new habits in a step by step narrative in her six volume books. The Waldorf method aims to achieve the same thing through rhythms. Daily, seasonal and yearly cycles help develop habits that are naturally achieved through environment.
See other excerpts of the lecture to understand more on the differences between the two philosophies.
I do add my own experience and knowledge to my talks, so it may not be fully authentically Charlotte Mason or Waldorf.
