Welcome to the circle. I had the benefit of starting this as it was being released so I didn’t have the problem you’re having. Each month, Bruce released the audio for that month. Some months, there were several audio files, while towards the end of the series he just did one audio lesson each month. Many of the audio lessons specify exactly how long to practice each component, sometimes broken down into just a few days on a given. Some months have a single practice.
If you download the material from each month following this month-by-month organization, you’ll find Bruce’s directions very clear on how to proceed. It’s really well-laid out and I found it a really effective foundation to my meditation practice.
If there’s a specific question, please post it to the group. thanks
Good luck with your practice.
