Friendship.

There are not many selves, there is only oneself not wanting to be by itself. The purpose of self it is companionship, the purpose of self it is friendship, the purpose of self it is love. All this so not to be alone, so to experience warmth and togetherness. Now what is there thus to be anxious about? Now what is there thus to fight over? Nothing! All this is self and the purpose of self is love.
