Malana village is located in the Kullu Valley in Himachal Pradesh. Jamlu Deva a manifestation of Rishi Jamadagni is worshipped in the form of Khanda. Story of Jamlu Devta of Malana is as follows:
Rishi Jamadagni was supposed to have been carrying eighteen images of gods – symbolic representations of the world gods – with him, while searching for an idyllic spot to meditate.
A gush of whirlwind scattered the images of gods all over the Beas valley, each image becoming the God of that area.
Jamlu devta is the Lord of the assembly of the gods, communicating through Gura (his disciple) in trances.
The whole community contributes a share of their income to the treasury of Jamlu Devata.
Another story about the Jamlu Devta of Malana
Jamadagni Rishi performed intense penance and propitiated Shiva. Shiva appeared before him and as boon, the Rishi asked Shiva for a secluded and peaceful place to meditate. Shiva asked to go to Malana.
Two brothers of Jamadagni Rishi followed him. He turned them away by gifting the regions of Lahaul and Banjar Valley.
When the Rishi reached Malana it was controlled by Banasura. The demon was not ready to give away his place to the Rishi.
A fight ensued between Jamadagni and Banasura.
The fight continued for several days and there was no clear winner.
When both of them could no longer fight, they decided to live in the village together.
Administrators of the village were selected from the group of Banasura. Justice was in the hands of Jamadagni Rishi.
Over passage of time, Jamadagni Rishi became powerful. But even today respects are paid to Banasura during village festivals.
About Malana and its People
Located at about 12,000 feet, Malana has been a veritable forbidden kingdom for eons. The nearest town is Jari.
The light-eyed residents of Malana claim they are descendants of the Greeks, and steadfastly believe their ancestors were Alexander's soldiers who struck roots here after invading India in 326 BC.
The villagers speak a distinctive Kanashi language (resembling the one spoken in Lahaul).
They have stayed aloof from the locals and Himachali culture. They consider themselves superior and marry among their own to preserve the purity of their race.
They have also remained independent of the local administration and government, instead having their own panchayat system in place, and boasting of themselves as the world's oldest democracy.
Their well-organized parliamentary system is believed to be guided by their deity, Jamlu Devta, who also presides over a primitive system of justice. (source - about Malana and its people)
