Exactly how power of will works isn't really understood in any meaningful scientific sense, it's simply something we know you can do and can practice to get good at. Simple breathing exercises to maintain focus, or to encourage calmness or energy are well known and certainly can have a measurable effect on heart-rate and some other physical indicators, but how you could, for example, ignore pain isn't something for which there's a concrete scientific explanation because the scientific understanding of consciousness and the brain are so very limited.
