Can you compare how Chapter 48 describes Sai's manifest and unmanifest forms with the descriptions provided in Chapter 30?

The provided text from Chapter 48 discusses Sai's manifest and unmanifest states but does not offer a comparison with descriptions from Chapter 30. Within Chapter 48, it is explained that even after Sai's form merged with the Unmanifest and attained formlessness, his quality as a benefactor to devotees did not end. It highlights a continuity of his grace, noting that 'Whatever actions were performed while in the body, the same are experienced today in the Unmanifest state by those who are devoted to You.' This demonstrates that his protective nature persists beyond his physical presence, a key theme of this section of Chapter 48.
