Yeah! It's a cycle of reincarnation. We're all part of the same spirit, but we're all different people at the same time. I can't do it here in Luceti, but back at home? I could make the spirits of my past lives appear for me to give me advice, or to teach me about their lives. [It's not always been advice he's wanted to hear, and last time he was home he burned one of those bridges; but Aang's one to often gloss over the negative when he can.]
