At this point, you may find it helpful to learn to work with awareness practices. I am especially fond of my friend Michael Ashcroft’s Fundamentals of Alexander Technique course, which shares a mindfulness- and awareness-based approach to Alexander Technique that he studied under Peter Nobes. I’ve also heard excellent things about the approach taken by the Evolving Ground community (e.g. their recent Opening Awareness book), which is based on Vajrayana Buddhism.
