Have you tried it? If you did you will realise that actually it isn't our attachment to distinctions that propels us, but there is an automatic animal decision making process before we rationalise about it. We actually do this a lot but we just don't realise it, afterwards we think that our rational sense of "I" is in the driving seat but really it is a bit different. As I said, it's hard to believe that you could live a life like that, but I promise you that after dropping distinctions you will handle the person shouting at you or the bear attacking you far more effectively than you would if you were rationally deliberating over it. But you'll have to try it to believe me perhaps, I was surprised too. Part of the reason why enlightenment is a long and difficult process is because we are so convinced that we need to hold onto things to keep surviving. Some people are so shocked by the realisation that they even commit suicide, particularly if done in an unsafe setting without support.
