Zen Master Taisen Deshimaru said:
You don’t need to tell yourself, “I’ve got to become Buddha”,
You have got to experience satori,
If you’re twenty or thirty years old you must understand
The satori of a young person.
But satori, what is it?
Simply truth,
Understanding the cosmic system,
Cosmic truth,
And you cannot harmonize with the cosmic system
Until you have let go of everything.
