Formal Zen koans are short stories or statements by past Chan/Zen masters which have been passed down through the generations for study and contemplation by Zen students. Each koan contains a Dharma teaching, and until you personally experience and digest that teaching, the koan remains a closed gate you need to pass through - on the other side of which is greater freedom, wisdom, and compassion. I discuss "natural koans," or Dharma gates that arise in our everyday lives, and how to work with them.
