Aang's relationship with his past lives plays a significant role in shaping his journey as the Avatar. By connecting with his past lives through meditation and seeking their guidance, Aang gains wisdom, advice, and new perspectives that help him navigate challenges, make tough decisions, and learn from the experiences of his previous incarnations. This connection allows Aang to draw strength from the collective knowledge and experiences of all the Avatars who came before him, empowering him to fulfill his role as the bridge between the human and spirit worlds.
