For me, the attraction was the spirituality part. I think most religions, at their core, start out with trying to give you a ritual to honour that 'feeling of feeling at one with the world', which, btw, you often achieve in meditation. There is a sense of belonging and feeling at one with the universe/every other living being in the world, like you're energetically connected - at least, for me.
And that in and of itself, can profoundly affect the way you look at the world, navigate life and handle the challenges it throws at you. It shows you how to handle the big Unknowns (like death) and focuses you on being in the moment and relishing every minute of it. In a way, it mimics the way two people trust in each other, when they're in a relationship - they become a team. It becomes like a trust in yourself and in the universe kind of relationship, where you're able to be confident in your ability to handle anything without being hyper vigilant, while trusting and understanding the way the universe works, because it *feels* right - because you're a part of it and you share that bond. You're not on the outside looking in or in an us vs them situation. You're working *with* the universe, instead. You're no longer stepping on each others toes during the dance - you become one.
...not sure if that makes sense
I think, along the way, perhaps due to peer-pressure and the need to be right, and yes, political power, the purpose of (organised) religion and those rituals got changed and, yes, in some parts, corrupted, and it got an extra purpose where it became a way to control, guide and harmonise a tribe. That in and of itself certainly has its purposes, but it's not what spirituality is about, imho. Although, I guess you could argue 'As above, so below', iow, feel in unison with the worldly world as well as with the spiritual realm. It's just that you don't have those downsides like worldly power abuse, that then overtake the original intent, in that spiritual realm
I also think that when that original spiritual part is lost due to the struggle for power and the need be right, it takes the religious/spiritual aspect right out of it, no matter how much that part gets invoked as a justification, because it goes innately against what spirituality is about, ime
