At the time of Marriage, king Janak had gifted a magnificent treasure of gems and jewels, after marriage those gems and jewels looked like a hill that is why this place is called ' Mani Parvat' even today. In the rainy season our most revered Sita and Ram ji used to come here for enjoying swinging. Even today, swinging on Hariyali Teej is the tradition.
