Bhante Vimalaramsi looks into the subject of Right Understanding (which he renames as "Harmonious Perspective"). A different perspective is considered for the 8-fold path. He then looks within the sutta itself and shows how the Buddha takes apart and analyzes the links of Dependent Origination. This is the most important teaching of the Buddha. It is said that one may even attain awakening by understanding these ideas on a deep level. This material won't be found elsewhere and, is in fact, radically different from other teachers explaining the Buddhist teachings. Do you really know what the 8 fold path is. Take a look at this very different set of ideas. Bhante Vimalaramsi only teaches from the Suttas and sets aside all the later commentaries and this makes for different results!
