That I have rated everything with Very Good may sound exaggerated, but that's how I feel.
Thorsten leads confidently through the course, is humanly pleasant and has, also important, a pleasant voice that guides you through the meditations. He was a participant in the ReSource project (you can google it), which makes him additionally competent. I have stuck with him ever since and meditate daily. You can book him without worries, you will not regret it. I wish you positive effects, they will come, which, is a surprise for each participant.
