Here are other ways to achieve this:
* Limited third-person: This narrator focuses on one character's perspective, revealing their thoughts and feelings while keeping others' inner worlds hidden.
* Free indirect discourse: This technique blends the narrator's voice with the character's thoughts and feelings, giving the reader a glimpse into their mind without explicitly stating "he thought" or "she felt."
* Internal monologue: The character directly addresses the reader, revealing their thoughts and feelings in a stream-of-consciousness style.
* Dialogue: Sometimes, characters' unspoken thoughts and feelings are implied through their words, tone, and body language, allowing the reader to infer their true emotions.
While an omniscient narrator can directly access and share the thoughts and feelings of multiple characters, other narrative techniques can be used to achieve the same effect with different levels of intimacy and depth. The choice of technique depends on the author's purpose and desired effect on the reader.
