Just saving something I came across while reading to centre myself a bit
Enlightenment is blissfulness with awareness. Knowledge is a passage; it is a journey. You have left ignorance, but you have not achieved enlightenment. You are in between. That is why knowledge is a tension. Either you fall back from knowledge or you go beyond. And falling back is not possible. You have to struggle to go beyond.
I feel like I'm in the middle bit with dbing - I know there is more to this journey, but every now and then the peaks and valleys are just too daunting. Hence the tension, conflict, inability to handle pain.
