I hope you don't expect any satisfying answer to this question from a blog post. 😉 I will nevertheless share my "understanding" of love with you. I've experienced love on many levels, as a child, as a teenager, as a man and with lots of psychedelics beyond the realm of age, gender or words. Here's what I remember and made of those experiences.
There are (at least) two kinds of love: conditional love and unconditional love. Like with freedom conditional love is, well, conditional. What conditions you put on your love is totally up to you. And what conditions others put on their love is up to them. A thrilling game in my experience, not rarely painful too.
And unconditional love, well, is unconditional which again means that there's nothing to be done about it and therefore also nothing to talk about. IF such a thing as unconditional love exists, and from what I remember from my psychedelic journeys, it pretty likely does, it simply is. That doesn't sound too thrilling, right? Yet, I'd not dare to claim that my experience of unconditional love was IT. It was AN experience of something that's beyond words and when I reach out to my old friend Logic, it says that IF unconditional love simply is, then THIS is also IT. Whatever I experience in this very moment is somehow unconditional love. I don't understand it and I don't know it but chances are very high that this is somehow part of the truth.
