The summit of Mt. Everest is so narrow and so perilous that it must be made without any assistance. A sherpa cannot hold your hand as you put one foot in front of the other, or catch you if you begin to stumble.
We reach a point where we are beyond help. This can be seen as scary, empowering, or both.
If we want to go far enough, our practice must incorporate this understanding, otherwise we will be ill prepared during the final stretch.
One sign we are reaching this rarified altitude is the internal prohibition from the wanton asking of questions (to others).
You must learn to be the answer to the question. Otherwise, dependency and attachment.
