Adi Sankara and the Frog
Baba Rampuri tells the story of how Adi Sankara established his main monastery, Sringeri Math, and the Temple of Sarada Devi, where he witnessed a pregnant frog trying to cross the deadly hot sands in the noon day sun, trying to reach the river.
He, thus found the “signature” of Sarada Devi, Goddess of articulation and knowledge, and it was there that he built her temple.
