Lauhavana is one of the twelve sacred forests of Vraja which the Puranas say, is a place where all vices can be destroyed. The forest of Lauhavana, also called Lauhajangavana, was especially well known for the many varieties of aromatic flowers that formerly grew there that created a wonderful fragrance throughout the entire forest. Lauhavana has an individual parikrama of about four kilometers, although hardly any trees remain of the vast forest that once stood here. The Adi-varaha Purana says that at one time this forest fell under the control of a demon named Lauhajangha, also known as Lohasura; therefore the forest became known as Lauhajanghavana and formerly covered both banks of the Yamuna. The fact that the Lauhajanga demon live here is also confirmed in the Gopala-tapani Upanishad. It is also believed that Lauhavana was the site where Krishna defeated the army of Jarasandha eighteen times. The forest is also called Lohavana as well as Loban.
Lauhajangavana was one of the forests where Krishna and Balarama would graze Their cows and where They enjoyed playing water sports in the company of their cowherd boyfriends in the lake known as Krishna-kunda. During the course of His pastimes here, the Bhakti-ratnakara says that Krishna slew the demon Lauhajanghasura and rid the forest of his menace forever. The places of interest here are the celebrated Krishna-kunda, the ancient Gopinatha Mandira, and the Lauhajangha Gufa, or cave where the demon supposedly lived and which is said to have gone underground for many miles. One can also see what is believed by locals to be the lower part of the demon’s body, after it was cut in half by Krishna. Local panditas say that when the demon was cut in two, the upper part went to heaven while the lower part, which was made of iron, remained on earth, and which locals now worship as an expansion of Shanideva, the demigod of the planet Saturn. The word ‘lauhajanga’ means that the demons ‘thighs’ (janga) were made off ‘iron’ (loha), or that his thighs were as strong as iron. There is a sandstone rock which supposedly represents Lauhajanga’s lower torso and thighs, which is worshiped with all the paraphernalia used in the worship Shanideva (Saturn).
