I was just watching a movie about sai baba and the showed that Meera bai(Shree Krishna Devotee) met sai baba when he was at shirdi . Is this true and how old is this history? Is this during the time where technology had already evolved well that history could be well documented?
Meera bai lived between 1498- 1546. Sai Baba was from late 19th century and early 20th century. Obviously they didn't meet.
There is a devotee of Krishna named Sundari bai Kshirsagar who was travelling many pilgrimages in India and reached Shirdi. She became to Shirdi with a statue of Radha Krishna. Hence she was named as Radhakrishna mai by Sai Baba. Her attire in the movie is similar to Mirabai. You might have got confused between the two.
