This covers all human beings, and dolphins should be given the benefit of the doubt. For the sake of simplicity I just call neighbors human. No one is above a human except God. The verb love in this instance means to want the best for someone, to want them to do well physically, but more importantly spiritually. And if possible, to do things to help someone be well or happy, especially spiritually.
All human souls are equal, unique, beautiful and incomparable.
We each create and shape our souls every day by the decisions we make. Depending on the interface, a soul could be a garbage man or a Supreme Court Justice. A soul lives forever, but a soul that loves things more that life lives isolated, alone in a world without love of life. I have seen this place. I would not wish it on anyone in the world, ever.
