The "jet-airplane route" to Self-realization. And that breathing technique - the one that sounds impossible - finally explained.
"You breathe in through the nose making a sound - that sounds impossible. How do you make a sound while breathing in?"
Let's answer this clearly before anything else.
Here's the thing that makes it suddenly click: the sound in Ujjayi (oo-jai-ee) breath is not made in your nose. It's made in the back of your throat.
Your nose is just the channel. The sound source is the glottis - the opening between your vocal cords in your larynx. When you slightly constrict that space while breathing, air passing through creates a soft, oceanic sound in both directions: in AND out.
Think of it as breathing with a very slightly "whispered" quality - like breathing onto a cold window to fog it up, but with your mouth closed and the breath coming through your nose.
The most common description. A gentle "shhh" or "ocean" sound - rhythmic, soft, continuous. You can hear it clearly if you listen, but it doesn't disturb anyone nearby.
Not snoring - lighter than that. The soft breath sounds you make when deeply relaxed. Ujjayi is the conscious version of what happens naturally in relaxation.
Or like the "haaaa" sound someone makes when they see something beautiful - except sustained as a breath, through the nose, both on the inhale and exhale.
He called it a "motor-like sound" - smooth, consistent, mechanical. Not breathy and irregular, but controlled and rhythmic like an engine running smoothly.
The slight glottis constriction in Ujjayi breath does several things simultaneously:
In yogic physiology, the glottis activation is also said to:
💡 Once you understand that the throat (not the nose) makes the sound, the technique goes from "impossible" to "obvious." It's the same mechanism as whispering.
Kriya means "action" or "deed." In this context, it refers to a specific action: consciously directing life force (prana) up and down the spine, magnetizing the spinal centers (chakras) and progressively withdrawing consciousness from body-identification into soul-awareness.
Yogananda called it the "jet-airplane route" to God-realization - claiming that sincere practice can achieve in one year what ordinary spiritual effort takes many lifetimes to accomplish.
His claim was bold: one Kriya (one complete breath cycle) equals approximately one year of natural spiritual evolution. He invited skeptics to test this themselves rather than argue about it.
"Kriya Yoga is the scientific technique that leads to the realization of God. It is the highway to Self-realization." - Paramahansa Yogananda
Observe the breath passively. Watch thoughts arise and pass. Repeat a mantra. These are excellent - and slow. Consciousness is being gradually redirected inward.
Actively manipulates prana. Instead of watching the breath, the yogi is consciously steering life force through the spinal column. It works directly on the subtle anatomy - the energy channels and chakras - rather than just on the mind.
This is why Yogananda compared ordinary meditation to walking and Kriya to flying. Same destination; very different vehicles.
The complete technique requires formal initiation. What follows is the publicly described framework — enough to understand what's happening and why. The living transmission adds what words cannot convey.
Yogananda's 39 energization exercises are done first. They consciously direct prana into every part of the body using tension and relaxation. The purpose: remove physical tension, teach conscious prana control, create the calm-yet-alert state needed for deep meditation. Takes 12–15 minutes.
Concentration on the natural breath, mentally tracking the sounds "Hong" (inhale) and "Sau" (exhale) — Sanskrit words meaning "I am He" or "I am Spirit." No manipulation of breath, just watching. This calms the mental chatter and prepares the mind for deeper practice. Usually 15–30 minutes.
Listening for the cosmic sound (Aum/Om) in the right ear. This is the "sound of creation" — described as a deep humming, roaring, or music-like sound that becomes audible in deep meditation when the external senses withdraw. Connects the practitioner to the vibration underlying all of creation.
The central technique. Using Ujjayi breath (the throat sound explained above), the practitioner visualizes and feels prana moving up the spine from the coccyx to the brain on the inhalation, briefly focusing at each chakra, then down the spine on the exhalation. One up-and-down circuit = one Kriya. Beginners do 12–24 rounds; advanced practitioners may do 144 or more.
After the Kriyas, the practitioner sits in stillness and allows the practice to settle. This is often where the deepest experiences occur — the mind has been thoroughly quieted, and pure awareness may shine through. Sometimes this is the most important part.
Prayer, chanting, or simple gratitude. Sealing the practice with devotion and consciously offering the fruits to something larger than personal gain. Yogananda considered this essential — technique without devotion was mechanical; devotion without technique was emotional but scattered.
A full Kriya session runs 30-90 minutes, sometimes longer. Yogananda taught daily practice as the foundation. "Even 15 minutes of deep practice," he said, "is worth more than hours of scattered effort." Quality of attention matters far more than duration.
In yogic anatomy, the spine is not merely a physical structure - it is the axis mundi, the "tree of life" of the subtle body. Three primary energy channels (nadis) run through and around it:
Kriya practice aims to balance Ida and Pingala and redirect energy into Sushumna - the central channel that leads directly to higher consciousness.
🧲 Magnetizes the chakras - charging them like batteries, awakening their latent faculties (intuition, compassion, cosmic consciousness).
🔥 Burns karma - Yogananda taught that accumulated karmic patterns are stored in the spinal centers as "seeds." Prana circulation literally dissolves these patterns before they can sprout as life circumstances.
🧬 Rejuvenates the nervous system - measurable physiological effects: reduced heart rate, lower oxygen consumption, slower brainwave activity, and what researchers call a "metabolic holiday" state.
🌅 Withdraws consciousness from the senses - progressively freeing awareness from its default entanglement with sensory experience, until the soul recognizes itself as something that exists independent of the body.
Kriya is not just a technique - it includes a direct energetic transmission from the initiated teacher to the student. This "shaktipat" (awakening touch/gaze/intention) is what activates the practice at a level that reading instructions cannot achieve. The guru acts as a living channel.
Powerful practices can destabilize unprepared practitioners. The formal initiation channel provides ongoing support, correction, and protection. Yogananda's SRF continues this function - initiated students receive guidance across their lifetimes of practice.
Written descriptions (including this page) convey the concepts. But the precise physical details - exactly how to position the eyes, the exact degree of glottis engagement, the precise mental imagery - these require person-to-person transmission. Some things can't survive compression into text.
SRF requires students to practice Hong-Sau, Aum technique, and Energization exercises for six months to a year before receiving Kriya initiation. This isn't gatekeeping - it's preparation. The ground needs to be ready for the seed.
Common experiences reported by sincere, long-term Kriya practitioners - across cultures and traditions.
Deep, stable peace that persists beyond the meditation session - a background calmness that doesn't disappear when life gets complicated.
Spontaneous intuitive knowing - insights arising without deliberate reasoning. Decisions becoming clearer. The sense that something wise is operating beneath the chattering mind.
Experiences of light and sound within the body during meditation - the inner light at the ajna chakra, the inner Om sound (sometimes described as bells, wind, ocean, or music).
Spontaneous withdrawal from body consciousness - the sense of being awareness itself, temporarily unbounded by physical form. Varying intensities, from subtle expansion to complete transcendence.
Reduced need for sleep and food - long-term practitioners often report that their need for external energy sources decreases as internal prana supply increases. Yogananda taught this directly.
Expanded compassion and love - the natural result of ego boundaries softening. Many practitioners report the gradual dissolution of habitual selfishness without effort or moral instruction.
This page explains the concepts. The actual technique is taught through formal initiation by Yogananda's organization.
