Learning begins with the perception of an object of learning by our sensory organs. Some objects may reveal all details of interest to us while the others may not fully satisfy our curiosity. We
We keep on revisiting the memory of those objects as we go on with our lives. This process is called reflection. We may want to sit in a quiet place to reflect on the memory of the object to learn more about it. Reflection may reveal all those details of our interest which were not perceptible to our sense organs and leave us satisfied.
There may be times or objects so profoud that we are not satisfied with the results of our deepest reflections. In those cases, our only recourse is contemplation.
