I consider myself to be just one among 7 billion human beings. If I were to think of myself as different from others, or as something special, it would create a barrier between us.

If the basic human nature was aggressive, we would have been born with animal claws & huge teeth -- but ours are very short, very pretty, very weak! That means we are not well equipped to be aggressive beings. Even the size of our mouth is very small. So I think the basic nature of human beings should be gentle.
