Boredom is actually a very positive sign. It is an indication that your meditation is beginning to wear through its entertainment value — ego is having a hard time finding fuel. Nevertheless, boredom is also a subtle or not so subtle manifestation of aggression. It is a dissatisfaction with the current situation and a desire for change. My teacher talked about two forms of boredom — hot boredom and cool boredom. Hot boredom is the irritable, wanting to jump out of your skin feeling that beginning meditators sometimes get. Over time, this can settle. Then cool boredom might arise. Cool boredom has an aware quality, a more subtle sense of lack of entertainment with highs and lows, less identification with “good” or “bad” meditation experiences. The best approach is to surrender to boredom. Let yourself be completely and utterly bored. Without giving you too much to look forward to, I will say that there are experiences beyond boredom. But you might have to give up hope.
