All this is Self and the purpose of Self is Love.

At any time, there is only oneself not wanting to be by itself. Now. When it comes to the origin- and purpose of the universe, earth and life — which is all self really — truth is unacceptably simple. Self has engineered itself to perceive itself as differentiated so not to be by itself. The purpose of self so to be able to experience companionship. Companionship being a synonym for friendship and love. As such the explanation for all phenomena. All phenomena are self. Self moves itself out of a two-fold desire: the desire not to be alone, the desire for companionship. All this so not to be alone. All this so to embrace oneself. All this so to experience companionship, friendship, love.
