Can you explain "Wishlessness" (one of the Three Doors of Liberation)?
The three doors of liberation -- by Vietnamese / French zen master Thich Nhat Hanh

I'm sure he says it a lot better than we could.

If we look at the three as identical and mutually supportive, we may see that with no self, and no form, the aspirants wishlessness is not for others. 

What zen master has nothing to teach their students?

Put another way, your nirvana is not my liberation -- so keep on practicing!
