Who is the narrator, can she or he read minds, and, more importantly, can we trust her or him?
First Person (Central Narrator)
It's easy as can be to identify the narrative technique in The Story of My Experiments with Truth because Gandhi uses the first-person pronoun ("I"), and the story involves his experiments with truth.
The story revolves around him, even though he's one selfless dude. We sometimes aren't sure who his family members and associates are because he tells us so little about them. Instead, we go inside his brain to hear his thoughts on religion, diet, and many other topics. So, this is definitely an example of a first-person central narrator.
