The dominant East-Asian [Sino-Korean-Japanese] flavor of C’han-Zen was given to it by its 6th Chinese patriarch, Hui-neng [638-713 CE] and his ‘Platform-Sutras‘ [T’an-cheng].
‘From the first Nothing is!’ roared Hui neng. [The story goes that the illiterate Hui-neng awoke to this conviction upon hearing the Diamond Sūtra recited just once at a public-square.]
A recent, widely-publicized survey solemnly titled: ‘The most important unresolved question of all time’, came up with Martin Heidegger’s celebrated query [itself, a variation on Aristotle’s ‘ti on’]:
‘Why is there Something and not Nothing?’
Very helpful. Smart people say the darnedest things.
