from within

Originating inside something

From within means originating inside something rather than coming from an external source.

Physical things emerge from within: Light glowed from within the cave.

More often the phrase describes internal origins—emotions, motivations, or forces: Change must come from within, The company was destroyed from within by infighting.

It emphasizes that the source is interior, not imposed from outside.
