Can you explain the practical differences between worshiping Sai's manifest form and his unmanifest form after he left his body? What specific rituals changed?

Chapter 48 of the Sai Satcharitra touches upon the transition from Sai's manifest, embodied form to his Unmanifest state. It states that even after leaving the body, his nature as a benefactor to his devotees continues without end. The text claims that the same actions performed while he was in the body are still experienced by his devotees in his Unmanifest state. However, as noted in Chapter 48, it does not provide specific details about any changes in rituals or practical differences in worship. The key message conveyed is the continuity of his grace and that his form, by merging with the Unmanifest, has attained formlessness, yet his support for devotees remains constant.
