I am on Purification level 3.
The first few years of Holosync posed an incredible challenge for me (not much fun in fact kind of hellish). I fought the growth every step of the way (hence the overwhelm/resistance).
For me personally it was worth it. I doubt I would have been willing to face all of that emotional baggage without being embroiled in it. The unrelenting stimulus was exactly what I needed at the time.
If you learn how to release resistance you will have an amazing skill that will come in useful in many areas of your life. Not many people look inward but that is where the biggest rewards lie <--- alright I will stop now...I am starting to get cheesy.
