Ramayana and Mahabharata refer to Pushkar Lake as Adi Tirtha, or the original sacred water-body. The famous Sanskrit poet and play-writer Kalidasa also referred to this lake in his poem Abhijñānaśākuntalam. The Ramayana mentions that Vishwamitra performed penance at Pushkar Lake for a thousand years. In spite of Brahma appearing before him and granting him the higher status of a rishi instead of a royal-sage (rajarishi), Vishwamitra continued his penance, but, the celestial nymph apsara, Menaka came to the lake to take a bath. Vishwamitra was enamoured by her beauty and they decided to live together in pursuit of pleasure for ten years. Then, Vishwamitra realized that his main activity of penance was disturbed. He, therefore, took leave of Menaka and went away to the north to continue his meditation. Vishwamitra was also described as building the Brahma temple at Pushkar after Brahma's yagna. Mahabharata mentions that Pushkar is a holy place of the god Vishnu, considered as the Adi Tirtha where millions of tirthas united during sunrise and sunset, and visiting the lake and taking a holy bath in the lake would wash off all sins.
