Samael Aun Weor gives certain exercises to develop willpower. For example if I'm not mistaken I think he gives one in Treatase of revolutionary psychology where I believe you rotate at the waist. What is this willpower? Is it the motivation one needs to actually do the work? Is it the will one needs to not give in to an ego when they know they need to observe onself, to meditate, to do a pranayama etc. Is this what the willpower developed with these practices is?
