In the Mahayana tradition, mindfulness is regarded as wisdom, transcendental knowledge, which is known in Sanskrit as prajna. Mindfulness is also a method of working with our mind. It is the method of recollection, of watchfulness, which develops into the stage of awareness. But if you look at this mindfulness and awareness, you will see that there is not much difference between them. Once you have developed the discipline of mindfulness, awareness is simply the continuity of that mindfulness.
There are several stages we progress through in our study and cultivation of prajna. These become the means for integrating our understanding into our experience, and progressively developing that experience into the full state of realization. In this article, I will discuss the four foundations of mindfulness as they are understood and practiced in the general Buddhist approach and in the Mahayana tradition.
