If I'm getting you right, I think [this is what you're looking for](https://help.obsidian.md/Linking+notes+and+files/Internal+links).
In short, you can use these formats for Linking your notes :-
1. Linking a separate note to your note :- `[[`notename`]]`
2. Linking a block on the same page as your note :- `[[^`any word from block then choose the correct one`]]`
3. Linking a block present in a different page :- `[[`notename`^`anywordfromblock`]]`
4. Linking a heading on the same page as your note :- `[[#`headingname`]]`
5. Linking a heading present in a different page :- `[[`notename`#`headingname`]]`
ps: you can use `|` before `]]` and in between them you can use any word to replace the tags given by obsidian
e.g, `[[`notename`^`block`|`example`]]`
