Hello Harry,
Here is a breathtaking perspective on the experience of the Avatar course from a 17 year old who just recently did the course.
"Avatar did not solve my problems. I did. Avatar did not show me myself. I did. Avatar did not scare me about what I would find out about myself. I did. Avatar did not force any effort or struggle. I did. Avatar did not rid me of my worries. I let them go. Avatar did not teach me how to love. It reminded me that I already knew.
Avatar showed me the door. I had to walk through it. I hope so many more people will take the steps I took. There is nothing to fear. Remember that you do it and no one else. You will love it on the other side of the door. I will not attempt to describe it, because that would be impossible. But you will know and recognize it when you have crossed the threshold. It is a place you have been before. Welcome home. You did it." - I.E., USA
