I was thinking about an example for this and thought about selfless service and noble purposes. It brought me back to a moment on 9/11/2001. There was a story of two men who traveled up the burning building getting everyone free so that they could get out. These two men kept on going as if they knew it was going to already happen. Would this be the ultimate for Karma yoga? There was somewhere else saying it would lead to Asamprajnata Samadhi which is the highest state? But really the sacrifice so ultimate as that.
