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—its hunger is not being satisfied, and so you satisfy the hunger with reading, talking, TV, internet, shopping, and/or actually eating needlessly.
When you stop and choose to bring awareness to the feeling, you will find that there is space and stillness around the feeling, and as the inner space grows, the feeling of boredom begins to diminish. 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, but it is simply a condition of the human mind that will come and go. Nothing that comes and goes is you.
The next time you notice you are bored and restless, rather than trying to satisfy that boredom by getting involved in an activity of some sort, try the following:
Stay bored and restless and observe what it feels like to be bored and restless—be curious about it and notice what starts to happen as you choose to stay with it.
