The mind exists in a state of “not enough” and so is always greedy for more. Boredom means the mind is hungry for more stimulus, more food for thought, and its hunger is not being satisfied. If you can stay bored and restless and observe what it feels like to be bored and restless, you bring awareness to the feeling and there is suddenly some space and stillness around it. So even boredom can teach you who you are and who you are not. You discover that a “bored person” is not who you are.
Boredom is simply a conditioned energy movement within you. Neither are you an angry, sad, or fearful person. Boredom, anger, sadness, or fear are not “yours”, not personal. They are conditions of the human mind. They come and go. Nothing that comes and goes is you. “I am bored.” Who knows this? “I am angry, sad, afraid.” Who knows this? You are the knowing, not the condition that is known.
