There are maps of practice. The six paramitas, the eightfold path, the seven factors of awakening, Zen’s ox-herding pictures. But from the point of view of our own practice, the real map of our own journey is only ever seen in retrospect. The map appears behind us, after we have taken a step.
The forward step is always, always into the unknown. If we know what’s coming, it’s not a growth or development in practice. And it’s certainly not awakening. Awakening and practice, experientially, are always out of what we know.
