Was Damu Anna actually trying to kiss Mavshibai, as she accused?

No, the texts in Chapter 24 indicate that Damu Anna was not trying to kiss Mavshibai. The accusation was made in jest by Mavshibai. During her vigorous service of massaging Baba's stomach, she was swaying back and forth, and her face happened to come close to Anna's. Seeing the opportunity, the humorous Mavshibai jokingly accused him, asking, "What, Anna, why are you following me? First, give me a kiss." Anna, a mature man over fifty, was angered by the false accusation, retorting that she was the one who put her face near his. The entire incident was a misunderstanding that Sai Baba humorously resolved.
