As Buddhist teachers often point out, knowledge, in the sense of prajña, is not knowledge about anything. There is no abstract knower of an experience that is separate from the experience itself.
Once we are bound together to our brothers by a common good that is outside us, then we can breathe. Experience teaches us that love is not to gaze at one another but to gaze in the same direction. There is no comradeship except through unity on the same rope, climbing towards the same peak.
