Daily life is what daily life is all about.
I do think I’d potentially be happier with a partner who I could speak philosophy and politics with, but if we couldn’t also function simply navigating running a household and raising our family, then we really couldn’t be anything more than friends with benefits long term. Not that that would be a bad thing. It just depends on how you want to move your life.
That “spark” is whatever consciousness is in the end I think. Everything else is subject to direct inspection and can be found to be deterministic or emergent, not actually subject to any kind of “will”. I speak also from insights gained while meditating (or doing psychedelics 🤗)
