They say it’s complex, confusing. But it isn’t, not really. Not when you get to the core of things. All things, at their core, have at least some quantity of love in them for something.
Once you understand this, even if only about a few things rather than all of the things around you, you can reach a state of mind sometimes described as a feeling of sympathy or affinity with something. The ability to care about other things. Be it a person, a cat, or even just a well-written book, all things have inherent value in some way, and that value is nothing more than how much you care for it. It really is as simple as that, this seemingly-complex thing called love. It’s our ability to care.
