Sat Kriya, along with Sodarshan (also in this course) is another one of the most powerful Kundalini practices, and was the first most important lesson that I gained from my own early yoga practice into the powerfully destructive tendency that we all have one some level, of perfectionism. Recognising and letting go of the immense pressure we all put ourselves under to be 'perfect' can be one of the most liberating gifts you can give yourself.
