It happens fairly regularly, I just noticed, that I sit calmly in my practice as primal terrors come up. I am not connected to them, even though of course I am. I have learned they have a texture that is neither good nor bad. It is THAT, and that can at times be very interesting.
Is a road connected to a car? They are related, obviously, but the one will never be mistaken for the other.
What makes roads useful? I will plagiarize Lao Tzu and say space. If they are filled, they are useless or slow.
