You sure can. Try not to have any expectations. Simply just listen to N.O.W.–it does the heavy lifting for you! In the beginning you’ll notice that you sometime pay attention to the N.O.W. tones and then at other times you are aware you are thinking about something. This is natural. But really quite special–when you realize you are not really listening, but thinking about something, this is an awakening… and it is the perfect moment to bring yourself back to just listening again to the tones. This IS the exercise of listening to the tones, coming back again and again when you notice your thoughts, and release them.
There is a huge world of positive change that is going to happen when you experience this, do the listening, and return to experience it again.
