When we recede into the depths of silence within us we arrive at the true basis of our life. The disciples can look within and get guidance only if they stop looking upon somebody outside for guidance.
What is needed is that you should turn your mind within, and the best thing for that is to remain where you are and practice the disciplines prompted from within and finally get divine illumination.
In this hall, there are four walls. It is not the walls we are making use of, but the empty space within them. In a vessel, which is the most useful portion? The empty space within it!
So, if you empty yourself completely, you create something like a vacuum within yourself. Then you are really full; you are most useful.
