Yes, I see it is a concept. A categorisation by the mind of some of the world that is seen. I think I was struggling for words. Looking at my cat (my closest non-human subject for observation!) I sense that there is no difference to the 'life', just different things being experienced - the experiencing 'I' have of this body, these thoughts, these actions/routine are likely different to the experiencing the cat has of her body, mind, actions/routines - but who knows? She can't tell me. (I certainly think it's absurd to think that animals are entirely different from 'us' - it seems that most people somehow forget that we are animals too! :-) )Being human is a concept, what if you simply drop it? Just for a moment.
Is there really a difference between you and a dog?
And who knows, maybe the differences between my experiencing and my cat's aren't any greater than between yours and mine.
