You know the story of the Zen novice. He went to see the master and asked how long it would take for someone like him
- a hardworking, determined intelligent person- to attain satori. He was prepared to give everything he had.
The master said maybe 15 or so years.
"But I mean EVERYTHING, I will endeavour night and day."
Master: "I see. In this case 30 or more years."
