Actually Allah said that there are two types of Quran verses, first is the easy understanding and the second is the non-easy understanding. Muhkamat and Mutasyabihat, I think you know that term, friend.
For instant, if ALLAH said in Quran that in heaven we will be put in a high place...the salafi type of person will see it just like really living in a short of higher ground like that, but in term of Tasawuf understanding (soul/psychology) it should be interpreted in a psychological way, like taking a superior mentality ( I think we all know the term of "inferiority complex of Adler"). This is only very short explanation.
The problem is in the Ulama side, the one that has authority to explain Quran and Hadist to common people. Many Ulama is not really Ulama based on Quran definition, and political ruler in the past and today can define which one can be considered as ulama and which one is not.
