Recall the well-known saying among Tibetan Buddhists that a pot with a little water in it makes a loud noise when shaken, but a pot full of water makes no noise at all.
People with very little realization often want to tell everyone about the insights they have experienced, the bliss and subtleties of their meditation, and how it has radically transformed their life. But those who are truly steeped in realization do not feel compelled to advertise it, and instead simply dwell in that realization. They are concerned not to describe their own progress, but to direct the awareness of others to ways in which their own hearts and minds can be awakened.
