Sati Ma had decided to take a test of Shri Ram. She had travelled with him for a long distance and walked ahead of Shri Ram while taking his test. That at time Shri Ram had called her as Yedai Ma. A Sati temple is located in Aermala, dedicated to this name. Shri Ram had a meeting with Sati Ma at this place.
