Reply To: No More Anxiety & Anger
As far as being safe, I have listened to both myself while doing so. What matters is that you listen carefully to what is being said and that you think about what is being said (not just let the words wash over you) and how it has applied in the past and/or will apply in the future to you as you listen to it while you really try hard to feel the feelings associated with those thoughts the entire time.
If you fall asleep, it's ok. I also used to listen to them on my daily walk. It's like exercising your mind and body at the same time.
