Throughout Yogananda’s “Autobiography of a Yogi,” it is clear that the goal of yoga can be summed up in its very definition in Yogananda’s index, “‘union,’ science of uniting the individual soul with the Cosmic Spirit.” Yogananda lays out a convincing case that man’s essential condition is to be trapped in “samsara,” which is the state of being convinced through all of one’s sensory experience that the whole of reality is contained in the illusory or delusional dualistic temporal world, known as “maya.” The purpose of yoga, on the other hand, is to attain a state of transcendence over samsara by experiencing the at-first temporary bliss of union with God, known as “samadhi.” The simple phrase, “from samsara to samadhi” (my words,) could encapsulate the gist of Yogananda’s teaching, which is in turn is a modern, Western-oriented presentation of sacred Hindu scripture. It is no accident that Yogananda quotes Ralph Waldo Emerson, America’s great Transcendentalist, frequently throughout the book.
An untrained Westerner might assume that the transformation from samsara to samadhi would occur through mysticism alone; that science would have no part of it. Thus it comes as somewhat of a surprise that Yogananda insists on the scientific basis of yogic technique, which he calls “Kriya Yoga,” or the (scientific) technique for attaining union with God. Yogananda expresses the utmost respect for both Indian and Western scientists and their achievements throughout the book, devoting a chapter to “India’s Great Scientist, J.C. Bose,” and another to his American friend, Luther Burbank, to whom he dedicates the book, calling him “an American saint.” He believes fervently that scientific method will in time demonstrate the reality and effectiveness of Kriya yoga’s meditation techniques, even if Western science never actually proves the existence of God or describes fully the nature of His role in the universe.
In the last chapter of the “Autobiography,” Yogananda summarizes the limits of scientific investigation by reporting: “ ‘Leave a few mysteries to explore in Eternity,’ Sri Yukteswar (Yogananda’s own master) used to say with a smile. ‘How could man’s limited reasoning powers comprehend the inconceivable motives of the Uncreated Absolute?’” Nonetheless, this simple admonition is the only statement I found in the “Autobiography” describing the limits of science. Elsewhere, Yogananda goes to some pains to portray his admiration for science and reasoning, mentioning for example that later in his life he came to accept or at least admire the teachings of his university philosophy professor, who was much put out by the student Yogananda’s inattentiveness in class. In Chapter 26, “The Science of Kriya Yoga,” he says that “Kriya is an ancient science…(that) had been lost in the Dark Ages.”
This emphasis on science is for me one of the most surprising and actually comforting aspects of Yogananda’s teaching because it implies emphatically that we do not have to choose between mysticism and science or between religion and philosophy. All three disciplines can be useful and valid. If anything, Yogananda de-emphasizes the mystical aspects of yoga, even as he tell stories of Indian saints such as the ancient, near bodily-immortal Babaji, which are as fantastic or incredible to a Western ear as anything in “The 1001 Arabian Nights.”
What are we to make of this? Obviously, there is no way at present to demonstrate or refute the scientific accuracy of Yogananda’s views or revelations on God. On the other hand, a growing body of research on such matters as changes to the oxygenation of blood cells during and after meditation may point in the direction of the scientific validity of yogic technique. Research in physics may be leading us closer to finding the elusive “God particle,” which is most likely inseparable from energy. Finally, a recent book, “The Akashic Experience: Science and the Cosmic Memory Field,” by Ervin Laszlo, points to scientific evidence for the “Akashic Records,” the mystical records described in Hinduism that purportedly catalogue the existence of every soul on Earth, throughout human history. It was these records that Edgar Cayce, the famous American psychic medium, was apparently able to tap into during his trance readings.
