Without patience, we cannot advance to a higher stage, for patience is the prerequisite for deep concentration and diligence. The two need to work together. Buddhism is neither conservative nor backward, but seeks daily improvement. Some says that Buddhism is no longer relevant. These remarks are erroneous because the people who said them did not know the Paramita of Diligence.
Progress is good, but more important is progress with diligence.
Currently, there are many great scientists in the west who have made many discoveries, they persevered, they did research everyday and never stopped. The same applies to learning Buddhism. We practice diligence when we choose one school or method and stay focused on our selection, studying until we excel in it, before advancing to another method. It is not possible to concentrate on different methods at the same time. Once we understand one method, we will understand all of them.
