You will experience uncertainty on the path. We can turn and hide from it, or learn to carry it into our practice.
In the beginning, turn it into a question. Use it as a marker for curiosity. Try to resolve it.
In the middle, allow it to refine your practice. Use it to find the edges and break them down. Allow it to give rise to dissonance and resistance so you know where to focus your attention.
In the end, no one has walked this path before. You are forging an new trail, uncertainty lies just around the next bend. Keep going.
