I know the Surangama Dharani is recited extensively in Ch'an. I've heard it said that it's also practiced in some Korean and Japanese contexts. Does anyone know where or when this is so outside of Chinese-language schools, that is, where & how it has been transmitted?
Thanks to the help of generous sponsors (most of them from DharmaWheel), I'm doing a Vajra Armor (Dorje Kotrab) self-retreat this summer. May the merit be yours!
