Look, I'm not going to say someone can't benefit from spirituality, just because you can benefit from something doesn't mean you should. No doubt, I could benefit from going back to college and taking a bunch of math classes.
But I'm not going to do that because I have other priorities.
But the inverse, saying that someone could not benefit from this, would be saying that said person does not have a Buddha nature. It would be saying that the person is somehow inferior - which I'm not going to say, because I don't believe that. I believe that every single one of you fuckers are Buddhas. You can be offended by that if you want to be, but honestly from where I'm sitting it's a sign of the utmost respect and admiration.
You might see it as me assaulting your own worldview or trying to coerce you into following mine, but that's not what I'm doing. I am making a simple statement about reality from my personal perspective. You being a Buddha, even if you're not a Buddhist, does not minimize what you believe now. It doesn't say that the way you look at yourself and reality is not valid, rather it says that there are other ways of looking at reality and yourself and from this perspective the truth of things is so much better than what we regularly imagine about both.
Plus, there's actual scientific grounding for this view. The more we actually learn about reality - the more we learn that our own perceptions are inadequate. Like did anyone see this TED Talk:
https://www.ted.com/talks/donald_hoffma ... anguage=enGuy talks at length about how evolution does not favor organisms who see reality as it is, rather our perceptions have evolved to function as a sort of "user interface" with reality - so the reality we see is more like a desktop on a computer - it's not actually the computer, it's an abstracted symbol of the computer created so we can more easily operate it.
Which again, is why faith is important sometimes - if our perceptions are not accurate, then we cannot depend on them alone and it may be that in order to become happy we have to reject certain aspects of our perceptions from time to time. Hence what The Buddha was trying to do from the beginning: conquer attachment to the wrong things, in order to promote a higher life-state with greater satisfaction than can be found chasing after our wants.
