I read there are 3 realms of samadhi: realm of desire, realm of form and realm of no form.
If I read correctly, Samadhi is one-pointed focus. But if I achieve samadhi by, let's say, the desire to win a sports game: I'm locked in, well doesn't my mind have to be focused on many aspects? There isn't a single-pointed focus, of having only one object like a kasina, in mind. Same for form. Can one still achieve one-pointed focus with multiple things in mind, if he is only focused on them and nothing else? Can I still reach happiness and the other jhana factors?
