The Returning curses pt1 AND pt2 is a complete aura cleaning method. The part 1 cleans the soul, the part 2 further cleans it and secure the cleansing.
Its not only clean it but returns the dross to the senders.
Me personally I only do the pt1 and the pt2 without affirmation, I just visualize myself clean and shining bright due to lack of time.
After the pt1 and, 2 you should also do a AoP.
These two, cleaning and protecting is necessary to anyone nearly in any level of advancement.
