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. That same year he founded Self-Realization Fellowship to disseminate worldwide his teachings on India's ancient science and philosophy of Yoga and its time-honored tradition of meditation.
Yogananda traveled and lectured widely, speaking to capacity audiences in many of the largest auditoriums in the country -- from New York's Carnegie Hall to the Los Angeles Philharmonic. The Los Angeles Times reported: "The Philharmonic Auditorium presents the extraordinary spectacle of thousands....being turned away an hour before the advertised opening of a lecture with the 3000-seat hall filled to its utmost capacity."
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.
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."
