Above all, don't wish to become a future Buddhaby Eihei Dogen
Original Language Japanese
Above all, don't wish to become a future Buddha;
Your only concern should be,
As thought follows thought,
To avoid clinging to any of them.
Note: I have not been able to track down the original source or translator of this verse. I found this on the Internet attributed to Dogen, but it is possible that it is not actually by Dogen. If you happen to know positively one way or the other, please let me know. Thanks.
