Zazen without zazen
Nishijima's approach is highly intellectual in nature, and aims to understand the Shobogenzo. In my opinion, the Shobogenzo reads like any other Zen writing in that it is not a compendium of 'Zen knowledge', but a means to point to the manifest nature of the human mind. True, Shobogenzo, which one can read excellent translations of at a site called the Soto Zen Text Project, is a compendium of Zen lore. However, this is not so much knowledge of Zen as it is a history or map of the Zen experience, which Dogen invites us all to experience in seated zazen in his Zazengi.
So I have not been able to sit formal zazen for a week or so due to circumstances, and have found the practice of what Hakuin Zenji called 'the continual spirit of zazen' to be most helpful. Essentially, the idea behind it is to let the mind sit zazen while interacting with the world. The principal Way here can be found in the 6th Patriarch's Platform Sutra, when he speaks of Prajna. To have an unperturbed mind, while reacting benevolently and in a focused manner to one's Karma---this is called t'so-ch'an by Huineng, for whom as I recall, seated zazen was not a means of Enlightenment. However, Huineng is the subject of one of Dogen's Shobogenzo essays, Old Buddha.
I would recommend anyone interested take a look at the Soto Zen Text Project, read Dogen there for free, and reflect on Warner's apparent need to manifest his 'Punk Rock Zen' via media and teaching appearances, as someone who 'understands Dogen Zenji'.
I realize this community has seen Brad Warner as a kind of hero, but in the interests of debunking hero worship in the tradition of Zen scepticism, I offer this as a thought to ponder, or rail against, or agree with. I just don't want to see this community die out, because zazen is truly beneficial, in my opinion.
