Those who emphasize inquiry for awakening seem to have friends rather than students (Byron Katie, Douglas Harding, etc).
In a way, this seems healthier than the usual teacher/student or guru/disciple relationship.
And more honest.
We are all explorers. We can all learn from each other, even if some of us are more familiar with the terrain than others. Less experienced explorers discover more for themselves with the help of pointers from more experienced explorers, and the reverse is also true.
At the same time, the process is always only individual - we each have to see for ourselves.
