i need some advice on how to start

hello. the first time i saw something about non-duality was on tik tok in 2023, the concept of this philosophy always seemed beautiful to me and i wanted to know more about it. some things that i read and watched were difficult to understand in that time. now, i decided to stop being lazy and i want to study this philosophy and live with that. someone can give me advices on how and where to start studying it?
