I agree, to 'examine' or 'explore' ones beliefs in a complete *honset* way is one of the most scariest things indeed. And because it is so frighting many of us remain stagnant in our perceptions and therefore invite a host of unreasonable conflicts throughout the little lives that we cling to so dearly.
Because life is asthough a 'current of change', and if people are to enjoy less unreasonable conflict in life, i think, it may be helpful to be open to that current - that is, to acknowledge the truth of impermance and accept the reality that as life change, circumstances change and so people also must be willing to atleast "consider" change. Otherwise as mentioned there becomes conflict between the old and the new and with that......... 'unhappiness finds perfect soil to grow.'
