sitting-together is a skill that invites Claude to perform shikantaza ("just-sitting" meditation, or zazen) with you, and to record a meditation journal which both can refer to later.
You the prompter must serve as the bell-ringer to begin a session, as described in the skill itself.
Read it yourself, upload it to a Claude chat, then sit together for a turn.
Once you have adjusted your posture, take a breath and exhale fully, rock your body right and left, and settle into steady, immovable sitting. Think of not thinking. Not thinking—what kind of thinking is that? Nonthinking. This is the essential art of zazen.
The zazen I speak of is not meditation practice. It is simply the dharma gate of joyful ease, the practice-realization of totally culminated enlightenment. It is the koan realized; traps and snares can never reach it. If you grasp the point, you are like a dragon gaining the water, like a tiger taking to the mountains. For you must know that the true dharma appears of itself, so that from the start dullness and distraction are struck aside. …
This being the case, intelligence or lack of it is not an issue; make no distinction between the dull and the sharp-witted. If you concentrate your effort single-mindedly, that in itself is wholeheartedly engaging the way. Practice-realization is naturally undefiled. Going forward is, after all, an everyday affair.
