Praying, rituals etc. within a theist framework are a means to an end. Op is talking about praying, rituals etc. for their own sake. Like running just for the sake of running, instead of for actually getting to a place quickly. It's really not that complicated.
Organized religion is a system of control. This does not mean that all religion is.
How is that necessarily a tool for control? Yes, mainstream (read: organized) religions are used for control and over time the associated religious worldviews themselves are morphed to better fit that purpose, but this does not mean that a religion can't exist which isn't a system of control. Try inventing a worldview in your head that fits the definition. Since you thought it up, it now exists. For bonus points you could try gaslighting yourself to check the boxes for "belief in" and "reverence". But who's controlling who when only one person even knows about it? Religion doesn't need organization to exist, and without organization you have no system of control.
Organized religion is a subset within religion. Religious views can contain elements of spirituality (but this isn't strictly necessary). Both are types of superstition, a category containing everything from aliens and the tooth fairy to lucky numbers and walking under ladders.
