The problem with provocative self-help books and approaches is that when times are good you can use them to bolster your hopes, but when you really need to settle your mind and move forward these approaches fall apart, hold you back, or when hope is slipping the approaches of the authors appear nearly worthless. There is no salvation soothing words from people that dont care, unless they are promoting their books or seminars, are an obstruction; life remains life, nothing can change that.
And while tapping into some form of internal energy to heal ourselves in an emotional and mental sense, and to manifest our desires in a physical sense, is pushed by authors and speakers as engaging in success, the reason it fails is that we, as a people, are unreliable when it comes to productively dealing with ourselves. How can a mind that is divided be of any practical use to manifest nirvana? It cannot. At best, what they are doling out has already been established in other forms of religion, or concepts of being, and even if the gurus could give each one of us the answer the truth is that we cannot implement it because we have no systematic method for dealing with our greatest obstruction to happiness ourselves and our own limited understanding of our existence.
