Paramahansa Yogananda was born Mukunda Lal Ghosh on January 5, 1893, in Gorakhpur, India, into a devout and well-to-do Bengali family..

It was in 1910, at the age of 17, that he met and became a disciple of the revered Swami Sri Yukteswar Giri. In the hermitage of this great master of Yoga he spent the better part of the next ten years, receiving Sri Yukteswar's strict but loving spiritual discipline. After he graduated from Calcutta University in 1915, he took formal vows as a monk of India's venerable monastic Swami Order, at which time he received the name Yogananda.

Yogananda began his life's work with the founding, in 1917, of a "how-to-live" school for boys, where modern educational methods were combined with yoga training and instruction in spiritual ideals. Visiting the school a few years later, Mahatma Gandhi wrote: "This institution has deeply impressed my mind."

In 1920, Yogananda was invited to serve as India's delegate to an international congress of religious leaders convening in Boston. His address to the congress, on "The Science of Religion," was enthusiastically received.
Yogananda emphasized the underlying unity of the world's great religions, and taught universally applicable methods for attaining direct personal experience of God. To serious students of his teachings he introduced the soul-awakening techniques of Kriya Yoga, a sacred spiritual science originating millenniums ago in India, which had been lost in the Dark Ages and revived in modern times by his lineage of enlightened masters.

In 1935, Yogananda began an 18-month tour of Europe and India. During his yearlong sojourn in his native land, he spoke in cities throughout the subcontinent and enjoyed meetings with Mahatma Gandhi (who requested initiation in Kriya Yoga), Nobel-prize-winning physicist Sir C. V. Raman, and some of India's renowned spiritual figures, including Sri Ramana Maharshi and Anandamoyi Ma. It was during this year also that his guru, Swami Sri Yukteswar, bestowed on him India's highest spiritual title, paramahansa. Literally supreme swan (a symbol of spiritual discrimination), the title signifies one who manifests the supreme state of unbroken communion with God.

During the 1930s, Paramahansa Yogananda began to withdraw somewhat from his nationwide public lecturing so as to devote himself to the writings that would carry his message to future generations, and to building an enduring foundation for the spiritual and humanitarian work of Self-Realization Fellowship (known in India as Yogoda Satsanga Society of India).

Yogananda's life story, Autobiography of a Yogi, was published in 1946 and expanded by him in subsequent editions. A perennial best seller, the book has been in continuous publication since it first appeared and has been translated into 18 languages. It is widely regarded as a modern spiritual classic.

On March 7, 1952, Paramahansa Yogananda entered mahasamadhi, a God-illumined master's conscious exit from the body at the time of physical death. His passing was marked by an extraordinary phenomenon. A notarized statement signed by the Director of Forest Lawn Memorial-Park testified: "No physical disintegration was visible in his body even twenty days after death....This state of perfect preservation of a body is, so far as we know from mortuary annals, an unparalleled one....Yogananda's body was apparently in a phenomenal state of immutability."
