The main thing with this method is...it is mindfulness in action. You can practice with eyes open or shut, so less chance to fall asleep. You can do it amidst much noise and distractions. It is best to do it during a long retreat ...at least ten days but a month would be better, and just do this technique, not swapping around with other styles. Walking can be fast or the slow Mahasi type. LP Teean did not use the 'noting' technique of Mahasi Sayadaw, but that doesn't mean you cannot, if you are a beginner to practicing mindfulness. Remember he had practiced for several years in various styles, so even a practisioner of the Mahasi style can drop the noting once they are familiar with being mindful.
I tell my students that mindfulness must be practiced continually.....little effort= little progress, no effort = no progress. I compare it to trying to put a satellite into orbit. The rocket need a certain energy and constant thrust to reach high enough to break free of gravity. If you launch a hundred or a million rockets which do not have enough constant thrust, every one will fail. You could do retreats all your life for a hundred lives, but without the effort to keep mindful as constant as possible you will fail to achieve escape velocity and reach the goal...(Stream-entry)....after which the hard part is over and you are on a certain trip to the moon....
