The koan is where you find it, or what you brought with you. But some koans recur, and have been found useful, as Skill in Means, for raising the Thought of Awakening, the Great Doubt, non-attachment, non-duality, compassion, wisdom, further skill in means, the Bodhisattva vows, and adherence to the precepts. In Zen monastic training, the Master may assign a particular koan to the trainee to meditate on, or may quiz a trainee or all assembled monks with a relevant koan, asking for a Word of Zen. The trainee can also bring koans to the Master in regular mondo/question and answer ceremonies.
Compassion, compassion, because of your great compassion.
The koan is always and everywhere non-attachment, no-self, karma of selfishness and unselfishness. Keep working on that, as meditation, and also to recognize it whenever it appears in daily life. For example, the news is much less bothersome when viewed through this lens.
Should we offer the merit of our training to horrible people?
Who needs it more?
Rev. Abbess Jiyu Kennett
Today I am bringing together a variety of koan collections, all gathered and commented on as Skill in Means over the centuries.
I have, of course, not read all of these, but I’m working on it. Slowly. Don’t think you can just read koans, like eating candy. Study in detail.
I don't say that there is no Zen; I only say that there is no master.

To do something yourself, without copying others, is to become an example to the world.
Kyojukaimon
If you are an example to the world, does that mean that others should copy you? There is a lot of it about, you know.
