Manasi Ganga is the largest lake or Kund in the central part of the Govardhan town. It is no different from river Ganga being manifested by the will (Manasi) of Lord Krishna. It’s said that one who bathes in Ganga is freed from all his sins but one who takes bath in Manasi Ganga is not only freed from sins but also attains the purest devotion of Krishna. The sacred circumambulation of Govardhan hill starts and ends at Manasi Ganga. The legend behind the origin of Manasi Ganga is that, once Kansa sent a demon to kill Lord Krishna. The demon took the form of a calf and hides himself within in the cattle group of Lord Krishna. When Krishna realized this, he killed that demon. As he had killed the demon while he was in the form of a calf, his cowherd friends refused to play with him and advised him to go and have a bath in river Ganga to purify his body of the sin of killing a calf. Unwilling to leave Braj, Krishna remembered Ganga within his mind and to his will Ganga took the form of Manasi Ganga and started flowing near the foot of Govardhan hill. Krishna then took bath in sacred waters of Manasi Ganga and purified himself to the pleasure of his cowherd friends. According to other legend, Krishna manifested Manasi Ganga through his mind (Manasi) to the pleasure of his foster parents Nand and Yashoda after knowing their desire for bathing in river Ganga and their unwillingness to leave the land of Braj.
