Baba Ganinath was born to Mansaram, who lived on the banks of the Ganga river in Mahnar, (now in the Vaishali district of Bihar). According to legend, he began showing miracles from his childhood. After seeing his miracles, the people praised Shiva and he was named "Ganinath". In Samvat 1024, he attended Vikramshila University and achieved mastery in eight Siddhis and nine 'Nidhis' with austerity and Yoga. He was married to Chandela king Raja Dhang's daughter Khema. The 5 children of Ganinath were Raichandra, Shridhar, Govind, Sonmati and Shilmati, respectively. After becoming king (Raja) in Vikram Samvat 1060, Ganinath unified the states won by his ancestor kings, to establish self-government and order in them. With love, coexistence and compassion, he integrated all the states into a single state. In order to liberate the society from Yavanas, he formed an army, which was headed by his sons Raichandra and Shridhar. Yavanas were defeated in the fierce battle. Sardar Lal Khan Baba, leader of Yavanas, influenced by Ganinath and became his disciple and served him throughout his life. Baba Ganinath Maharaj and Mata Khema took the samadhi together in Palwaiya Dham ( Palwaiya dhaam is center of worship for all Halwaai, Kaanu and Madhesia community), in Hajipur.
