The same chair some times irritates us, sometimes not. The chair is the same, but our mood has changed. The way we perceive people sitting around us also changes. At times we are disturbed by their coughing, at other times we hardly notice any sounds at all. Again, this has to do with the actualisation of underlying moods during medi ta tion.
Moods express themselves through our judge ment of the surrounding world.
It is surprising how objectively this can be perceived even for experi enced meditators. You are a stupid meditator. The chair is hard. People are making an enormous amount of racket. By turning our awareness away from the objective experi ence of the world, and towards the mood as a subjective phenomenon, we pass a threshold.
