The Reason for Diversity is Companionship.

The wise person says that 'all this is god' and so it is for 'god is'. It is this realization, this god-realization, which leads to self-realization. For indeed. All this is self. What it means is that self has conceived itself to perceive itself as differentiated so not to be by itself. The purpose of self is companionship. The purpose of self is friendship. The purpose of self is love. It is this what is the true meaning of biodiversity. Self is diverse for companionship, friendship, love.
