Dhyanayana
Dhyanayana Buddhism is what came over the mountains and implanted itself in the Daoist land-body, producing what would come to be called the Ch’an (transliteration of Dhyana) schools.
It’s not correct to say that Zen is Dhyanayana Buddhism. But look what Dhyanayana did.
“Yana” (vehicle) only became an apt metaphor once the comparative vehicles (“Greater” and “Lesser”) were dispensed with as Indian Buddhism dispersed.
Vajrayana Buddhism traveled quite well, too, and it’s arguably similarly inaccurate to say that some Tibetan traditions “are” Vajrayana Buddhism, just as in the Ch’an case.
These vehicles carried Buddhism out of the Yogic land-body, into new land-bodies indigenous to elsewhere.
Now, those new hybrid traditions have themselves become vehicles, like the ones that bore Dhyanayana and Vajrayana out of India.
They’ve come to the West.
Will they now find new land-bodies to implant in?
Are any healthy enough to receive them?
