I often come across highly qualified people falling an easy prey to fake Gurus or mysterious practices. There does not seem to be any relation between their scholastic achievements and their ability to judge things especially when it comes to so called spirituality. On the other extreme, I see self claimed Gurus who are apparently well read, failing to exhibit conviction and deeper insight.
The reason is – when it comes to spirituality, it is not enough to read. One needs to ponder over what is read, grasp the finer aspects of it and finally meditate on what is understood. Not only that, one needs to live a specific way of life. Only then one can get complete insight.
