I think perhaps universal love is the only real love, all else illusion and attachment. Universal love comes from recognizing oneself in all others, from realizing the non-dual nature of reality. It stems first from love of oneself, and then extends to all life. It's omni-compassion. Good-will without reason, motive, logic. It's the only stance where ones' feelings are truly unconditional. And it's not at all about ego. It's recognizing the suffering in oneself and in all beings, and wanting to relieve this suffering. Not because another is a friend of mine, or shares some of my blood, or may bear my offspring, or has the coolest personality, but because another, like me, is a conscious being thrown into this world against their will and made to endure the unimaginable pain that is existence.
