Alex, I am glad that you used "keep the mind from wandering off". I wonder what is the thing I need to keep my mind from wondering off? What is it that I need to think about when photo-flipping? I memorized chanting. I manged to maintain photo-focus for many minutes. My mind often goes to my hols, office, duties, all kinds of thoughts, also to "Am I doing photo-flipping right?", "Oh, where is my tangerine!?". What shall I be thinking of while photo-flipping?
