Maharajji was born in the village Akbarpur (Firozabad district) of Uttar Pradesh (India) in a wealthy Brahmin jameedar (landlord) family. He was born on Shukla Paksh Ashtmi in the month of Margsheersh and was named Laxmi Narayan Sharma by his father Shri Durga Prasad Sharma. From early childhood Maharajji was detached from worldly attachments. At the age of eleven he was married to a girl from an affluent Brahmin family.
Immediately after his marriage Maharajji left home and went to Gujarat. He roamed around various places in Gujarat and the entire country. After around 10-15 years (this is approximate and is as told by elders from village of Akbarpur) his father was informed by someone that he had seen a sadhu (ascetic) who was a lookalike of his son in the village of Neeb Karori (misspelt as 'Neem Karoli' at times) in the Farukkhabad district in Uttar Pradesh.
His father immediately rushed to the village of Neeb Karori to meet and get his son. There he met Maharajji and ordered him to return home. Maharajji followed his fathers instructions and returned. This was the beginning of two different types of life that Maharajji led. One that of a householder and the other that of a saint.
He devoted time towards his responsibility of a householder and at the same time he continued to look after his bigger family (i.e. the world at large.) However, there was no difference in his life and style of living when discharging duties of a householder or that of a saint. In his family as a householder he has two sons and a daughter.
He said that the whole world is my family (refer to the book 'Miracle of Love' by Ram Dass) and preached LOVE ALL, SERVE ALL, FEED ALL. He said this is the key to attain God and salvation. Maharajji was a born saint. He organized yagyas and bhandaras wherever he went. Both of these were organized simultaneously. Yagyas were to feed the God, and bhandaras were to feed the worldly people. He built Hanumanji’s temples at many places. Before attaining Nirvana he established two 'ashrams' (places for people to stay).
One is at Kainchi in Nainital district of Uttranchal and the second one is at Vrindavan in Mathura district of Uttar Pradesh. He selected Vrindavan as the place for his 'Mahasamadhi'. Vrindavan is the place where Lord Krishna played and lived. Vrindavan is also known as Golok Dham.
Maharajji left Kainchi Ashram on 09th September 1973 for Agra. This was his last visit to Kainchi and he left signs of his last visit which people could make out only later on. Description of the same is available in the book 'Miracle of Love' (by Ram Dass). On reaching Agra on 10th September, he immediately set for Vrindavan where he attained 'Mahasamadhi' on 11th September 1973.
