I hold the position that to be efficient one must do secondary research before being able to do primary research properly. To use a belief system or to have advanced spiritually through secondary sources doesn’t necessarily mean that you are simply believing what others are telling you.
This is perhaps...the reason why religious groups are often openly mocked online for unquestioningly accepting what they are told, in a perceived blind submission to authority. If this were the case, perhaps that is why so many Christians miss Jesus’s message (I infer this from indirect sources and personal experiences) and do not spiritually raise themselves (levels of consciousness). All too often people embrace a belief system mentally and outwardly but in reality are doing nothing more than showing subtle arrogance—the belief system cannot be embraced by someone with such little understanding and such a low level of consciousness.
The danger of religion then, is that these "believers" are falsely spreading the word of mystics (Jesus and Buddha for example) by their uneducated, unspiritually advanced manner and thought. If the teacher is weak, the student will be weak also. Therin lies the danger, in my opinion.
