Hey, I thought of something.
I'm sure the whole thing is more complicated than I can fathom, but I thought of something that applies.
The very best and strongest reason to love everyone is because of the healing that it enables.
We humans may tend to hold off and give love and forgiveness and compassion only when and to whom we feel It is deserved. But the healing power of love will not be fully unleashed if we hold it back from those who need it the most. Seriously, there are mysteries here more than what we humans can fully process. Love has the power to transform and we have the power to unleash this transformation, this transformative love.
It's like inertia, we set in motion our thoughts and feelings of love, compassion and forgiveness. We set these thoughts and feelings in motion and they go out into the universe and have a life all their own. There's a ripple effect. And it costs us almost nothing and does so much to make the world a better place.
The reason that I say it costs almost nothing is because we do have to go deep inside ourselves and let go of any hate, grudge or resentment or fears. We do have to let go of anything that may prevent love from flowing. But though we might think that these grudges and fears are important parts of ourselves that kind of thinking is not healthy. Because that grudge or hate or resentment etc that we may feel for that one person or that group of people, whatever, those negative feelings are holding us back from having all of the love and forgiveness and compassion that we could be benefiting from. Also fear. If we sent love, forgiveness and compassion out to all of these places and even said nothing out loud to anyone but only experienced it inwardly, privately, it would still have a ripple effect that could transform the world. And a transformed world, a world without hate and fear, is something that I believe is worth all of the effort.
