During the days of the Buddha himself he used to emphasize this point. One need not be a scholar and learn everything. Buddhism is not like studying a subject like mathematics where you have to learn all your theorems and different methods of working out the various types of problems. If you know the fundamentals, the basics, a scholarly detailed study is not an important precursor to pratice.
So out of this vast Buddhist culture, religion , or literature, or the vast body of experiences that come to us as Buddhism, each one of us would find that which is relevant to our life, to our type of problems.
