The source mentions Sai Baba's Samadhi doesn't waver even while he engages with the world. Can you elaborate on this seemingly paradoxical state?

Chapter 4 describes a unique state of being where Sai Baba remains internally detached while externally engaged. It mentions that he speaks with people, watches Murali dances, and listens to Gazals, yet his Samadhi, or deep meditation, "doesn't waver a bit." This suggests a profound ability to be in the world but not of it. The text further clarifies this by stating he "remains in the eternal state of the Self" even while he wanders to Lendi or the Chavadi. This points to a master who has transcended dualities, whose inner heart is as calm as the ocean, allowing him to participate in worldly dealings without ever breaking his inner knot of silence and equilibrium.
