Vishwaguruji was born on August 15, 1945, in the village of Rupawas, in the district of Pali, Rajasthan. His parents, Pandit Krishna Ramji Garg and Srimati Phool Devi Garg, both devout and religious people, gave him the name of Mangilal. As a young child, most of his free time he devoted to prayer and meditation. Whilst still in his teens, he was ordained as swami by his Guru, Hindu Dharmsamrat Paramhans Sri Swami Madhavanandaji, with whom he lives in ashram for several years, performing strict anusthana, spiritual practices.
On 10th April, 1998, Paramhans Swami Maheshwarananda was inaugurated by the World Religious Parliament as "Sarvabhaum Sanatan Dharma Jagadguru".
At the Maha Kumbha Mela in Haridwar, India (13 April, 1998) he was appointed as Mahamandaleshwar of Maha Nirvani Akhara.
In 2001 on the occasion of the Maha Kumbha Mela in Prayagraj (Allahabad), Swamiji was awarded with the highest spiritual title of Vishwaguru (Master of the Universe) in the presence of His Holiness Jagadguru Sri Shankaracharya Sri Swami Narendranandaji Sarasvati, by the Vidvat Samaj.
In the last 50 years Swamiji has travelled extensively throughout the world, tirelessly spreading the message of Sat Sanatan Dharma and Yoga according to the teachings of Bhagwan Sri Deep Narayan Mahaprabhuji. Wherever he goes he teaches people to understand and love themselves and others, and helps them to realise the sense and purpose of their life. His message is: understanding, respect and tolerance between nations, cultures and religions, non-violence, protection of nature and the environment and a vegetarian lifestyle.
Especially during the communist era, Swamiji's spiritual and humanitarian work provided great moral support to the people of the Eastern European countries of Czechoslovakia, Hungary and Yugoslavia. Due to his distinguished charitable, humanitarian, religious and environmental work as well as his untiring efforts for tolerance and world peace, Swamiji has been acknowledged by social, medical, religious and political dignitaries in many different parts of the world.
For his selfless efforts during nearly 20 years he received a letter of thanks by the President of the Czech Republic, Mr. Vaclav Havel. Croatian President Stipe Mesic acknowledged Swamiji's humanitarian service to Croatia over the last 30 years by awarding him the Order of the Croatian Star with the Effigy of Katarina Zrinska.
In his homeland of India, His Holiness Vishwaguru Mahamandaleshwar Paramhans Swami Maheshwarananda Puri has initiated several humanitarian projects. One of the biggest spiritual projects is the building of Om Ashram in Jadan, Pali.
In 1990, he laid the foundation stone of a large-scale project called the “Om Vishwa Deep Gurukul Swami Maheshwarananda Ashram Education & Research Centre” (commonly referred to as the “Om Ashram”).
The main purpose of this Centre is to promote the ancient Indian science of Yoga and the invaluable spiritual treasure of Vedic culture. This Centre is dedicated to the protection of all life, the environment and world peace. It hosts various charity events and supports education and healthcare.
