The Kriya Yoga technique is always preceded by a special breathing technique called Hong-Sau. These are powerful techniques. One hour of Hong-Sau is equal to going into a Trappist monastery, entering into a cell and remaining there for twelve hours praying unceasingly. Now, one hour of Kriya Yoga is equivalent to twelve hours of Hong-Sau. Why? The master explains that the natural evolution of mankind, the unenlightened masses will be enlightened through thousands and thousands of incarnations automatically as the earth rotates around the sun in three hundred and sixty five days going around the twelve signs of the zodiac.

similar occurrence takes place in your body. Your spiritual eye is the sun and the twelve signs of the zodiac are your six chakras, six up and six down and by polarity that makes twelve. It will require one million revolutions of the current going up and down the spine until every cell of your body has the proper frequency to receive the final charge of cosmic consciousness for enlightenment to come to you as a cosmic flash of light.

The masters devised a technique duplicating the cosmic motion of nature in exactly thirty one seconds causing a motion of current going up and down the spine giving you one year of evolution each time you do one Kriya technique, like the time machine of H.G. Wells, and if you can do one million Kriyas in one lifetime you can attain cosmic consciousness. There are thousands of people quietly practicing these sacred techniques all over the world and only those with good karma end up actually getting Kriya as you must practice the technique of Hong-Sau for several months to condition your body before you can practice Kriya Yoga.

A full explanation may not be given to the general public because of certain yogic injunctions, but it can be given from an authorized instructor of Self-Realization Fellowship in Los Angeles or Yogoda Satsanga Society of India. However a broad explanation must be sufficient. For more information see chapter 26, "The Science of Kriya Yoga" in the book Autobiography of a Yogi by Paramahansa Yogananda. This book has transformed the lives of thousands seeking the spiritual path.
