Keep in mind that Zen Buddhists do embrace the Pali Canon literature! However they practice a little differently while aiming for the same destination of nibanna.  The idea of having no expectations has been repeatedly stressed to me by my teacher who is a Burmese monk and teacher of insight meditation. We follow a more systematic method but along the way we intersect with Dogen’s teaching. It is so obvious at the end of the video that the monk is referencing the state of non self/ no self/ anatta. I really enjoyed this talk.
