Love is the eigenstate; it is the state of Oneself which we, Oneself, call(s) existence. What it means is that existence is Oneself experiencing itself out of Love. One's eigenstate is Love; Love is one's eigenstate. There's no formula for it as Love upholds Oneself; it thus already unifies us all for there is no such thing as division. We can, therefore, simply call ourselves 'Love'.
