Buddha is purported to have said 'Be unto yourself your own Buddha'.
This essentially means once you have grasped the basics, leave it alone and learn freely for yourself.
Anatta, a mark of existence, states that there is no permanent self. Again, once this is grasped, to be attached to anything is to add to the continuity of the self and therefore act in discord with not only anatta, but anicca as well.
I hope this paints the picture more clearly and will allow the discourse to develop, so we may all become closer to Buddhahood.
