Because it’s weird. With much of this inner work you need to move forward before you can look back to how you were before, so that you can see the changes you have made. Ten years ago I did not know that the phrases I would say to myself (“that was a stupid thing to do”, “don’t be daft”, etc.), where phrases my Dad had said to me. They just seemed like me talking to me. It wasn’t until I had removed the charge around my past that those phrases weren’t there anymore, my mind was quiet. Only then could I look back and say “wow, that was my Dad and he no longer lives in my mind like he used to”. So if I give too much deep information before people have experienced this for themselves, they have no way to relate to insight and understand that they can get there themselves.
