Paramhansa Yogananda was born as Mukund Lal Ghosh (also known as Swami Yogananda) in a Bengali Hindu family on January 5, 1893 in Gorakhpur, India. He showed signs of spiritual awareness even as a young child. His quest to find a great Guru to guide him in his spiritual path led him to Swami Sri Yukteswar Giri, who molded the young man who was to become a great spiritual force. After his college graduation in 1915, he took formal vows and was from that time on called Swami Yogananda Giri. Then in 1935, when he returned to India to visit his Guru, Swami Sri Yukteswar Giri bestowed upon him the title of "Paramhansa." The "supreme swan," of which this title is named after, is a mythological bird that can separate water from milk and drink the milk.

The book begins with his childhood and family life, then finding his Guru, becoming a monk and establishing his teachings of Kriya Yoga meditation. Yogananda's initial impact was truly impressive. But his lasting impact has been even greater. Yogananda's Autobiography of a Yogi, first published in 1946, helped launch a spiritual revolution throughout the world. His message was non-sectarian and universal. Yogananda's Guru, Swami Sri Yukteswar, sent him to the West with the admonition, "The West is high in material attainments, but lacking in spiritual understanding. It is God's will that you play a role in teaching mankind the value of balancing the material with an inner, spiritual life."

Yogananda brought clarity to hundreds of thousands of people regarding the ancient teachings of India - previously shrouded in the cultural assumptions and terminology of an era long past. He was the first yoga master of India to permanently live and teach in the West. Yogananda arrived in America in 1920, and travelled throughout the United States on what he called his 'spiritual campaigns' to teach the Science of Kriya Yoga.

The teachings of Yoganandaji centered on creating spiritual awareness in people. His lectures highlighted the importance of meditation, which leads the mind to liberation. Yoganandaji taught Kriya yoga, an ancient yoga system, to his followers, which He called the 'Jet-Airplane' route to God. Kriya yoga is an advanced pranayama technique, which revitalizes the life force in the brain and spine. Practicing Kriya yoga elevates the state of mind to achieve spiritual goals and feel oneness with Universe. He continued to lecture and write up to his passing (Maha-Samadhi) in 1952

Yoganandaji believed that all religions shared the same values. His lectures and writings made elaborate presentations on the unity of all religions. "The true basis of religion is not belief, but intuitive experience. Intuition is the soul's power of knowing God. To know what religion is really all about, one must know God." He further wrote that "Self- Realization is the knowing in all parts of body, mind, and soul that you are now in possession of the kingdom of God; that you do not have to pray that it come to you; that God's omnipresence is your omnipresence; and that all that you need to do is improve your knowing."

His association with nineteenth-century's Great Masters Lahiri Mahasaya and Mahavatar Babaji, who had prophesized the writing of this book and as well as how he travels across America lecturing and establishing his teachings in Los Angeles, California. Autobiography of a Yogi is an introduction to the methods of attaining God-realization and emphasizes the value of Kriya Yoga and a life of self-respect, calmness, determination, simple diet and regular exercise. It has been in print for the last seventy years and has been translated into over forty languages. It has been highly acclaimed as a spiritual classic and is designated as one of the 100 Most Important Spiritual Books of the 20th Century.
