Welcome to our next lesson. In our previous sessions, we have examined techniques that sit at opposite ends of the autonomic spectrum: the slow, coherent breathing of Zazen that cultivates parasympathetic tone, and the rapid, forceful Breath of Fire that elicits a strong sympathetic response. Today, we turn our attention to a practice that sequentially combines these different states into a single, structured protocol: Sudarshan Kriya Yoga (SKY).
Your goal is to build a comprehensive toolkit of breathing techniques, and SKY is a fascinating case study in how different parameters can be orchestrated into a physiological "symphony." This lesson focuses on deconstructing the precise architecture of this practice. We will map out its distinct stages, each with its own unique breathing rate, rhythm, and physiological intent. Understanding this structure is the necessary foundation for our next lesson, where we will critically analyze the clinical research on SKY's effects.
The Architectural Blueprint of Sudarshan Kriya
Sudarshan Kriya, and its longer variant Long Sudarshan Kriya Yoga (LSKY), is not a single breathing style but a sequence of techniques performed in a specific order. The practice is designed to first calm the system, then energize it, and finally lead it through a series of dynamic rhythmic cycles before culminating in deep rest.
A 2024 study on LSKY provides an excellent, detailed breakdown of the entire process. The researchers mapped out the full 60-minute practice, which we can use as our primary blueprint.

This paper from the journal Ancient Science of Life outlines the complete experimental protocol for a study on LSKY. It provides a high-level overview of the structure before diving into the specifics.
First, read the brief description of the procedure to get a sense of the overall sequence. Focus on the section Procedure for performing LSKY, which introduces the six main compartments (C1-C6). Then, look at the more detailed breakdown that follows, starting from the list of C1 to C6.
As you've just read, the practice can be broadly divided into these compartments:
- C1 & C2: Three-Stage Pranayama (Ujjayi) with rest periods.
- C3 & C4: Bhastrika (Bellows Breath) with rest periods.
- C5: Om Chanting followed by the core Sudarshan Kriya (cyclic rhythmic breathing).
- C6: Extended Rest (Yog-nidra).
This structure is visualized in the experimental protocol diagram from the study.
This sequence is not arbitrary. The discussion section of the paper proposes a physiological rationale: the initial Ujjayi breathing enhances parasympathetic activity, the subsequent Bhastrika stimulates the sympathetic system, and the rhythmic cycles of the Kriya itself are thought to repeatedly activate and deactivate both branches of the autonomic nervous system, thereby improving its regulatory flexibility.
A Granular Look at the Stages, Rates, and Timings
Having established the high-level architecture, we can now drill down into the specific parameters of each stage. For your "cheat sheet," these details—breathing rate, duration, and technique—are the critical variables. The same study provides a comprehensive table detailing every step.

This is the most detailed part of the paper for our current purpose. It provides the quantitative data for each phase of the practice.
Please carefully study Table 1, which starts with the text Shows details of stages. As you review it, pay close attention to the "Description," "Respiration rate (BPM)," and "Duration" columns. This table is the core information for understanding the structure of SKY.
Let's synthesize the information from that table into a more narrative format for your notes.
Part 1: Ujjayi Pranayama (Victorious Breath)
This initial phase focuses on slow, controlled breathing with gentle resistance at the glottis, a technique you are familiar with as Ujjayi. It is performed in three stages, targeting different areas of the torso.
- P1 (Abdominal Breathing): 8 cycles of Ujjayi breath, focusing on the movement of the abdomen. The breathing is very slow, at 3-4 breaths per minute (BPM), for a duration of 180 seconds.
- P2 (Thoracic Breathing): 8 cycles, focusing on the expansion of the rib cage. The rate remains at 3-4 BPM for 180 seconds.
- P3 (Clavicular Breathing): 6 cycles, focusing on the upper chest. The rate is still 3-4 BPM for 150 seconds.
- Rest: Each stage is followed by 30 seconds of spontaneous breathing.
This phase lasts about 10 minutes and is designed to induce a state of calm and parasympathetic dominance, slowing the heart rate and quieting the mind.
Part 2: Bhastrika (Bellows Breath)
The practice then shifts gears dramatically, moving from a calming technique to a highly activating one.
- Rounds: Three rounds of Bhastrika are performed. Each round consists of 20 rapid, forceful exhalations and inhalations.
- Rate: The breathing rate shoots up to approximately 20 BPM. Note that other sources, like the paper by Brown & Gerbarg, report rates of ~30 BPM, indicating some variability in instruction.
- Rest: Each 40-second round is followed by 30 seconds of rest.
This phase is a powerful sympathetic activator, similar in effect to the Breath of Fire you learned previously, designed to energize the system.
Part 3: Om Chanting & The Sudarshan Kriya
This is the central and most unique part of the practice. It begins with a brief transition and then moves into the eponymous Kriya.
- Om Chanting: Three repetitions of the chant "Om," which brings the breath rate to around 5 BPM, serving as a bridge from the high-energy Bhastrika to the rhythmic Kriya.
- Sudarshan Kriya Proper (Cyclic Rhythmic Breathing): This core component consists of multiple cycles of breathing at varying speeds—slow, medium, and fast—with no pauses between inhalation and exhalation. The paper by Brown & Gerbarg describes these rhythms clearly.

This paper provides a complementary description of the Sudarshan Kriya component, emphasizing its cyclical nature and defining the different rates.
Please read the section under the heading "Component IV—Sudarshan Kriya," specifically the paragraph that begins The fourth component. Note the description of the breathing as cyclical with no pauses and the three different rates used.
If you look back at Table 1 from the first paper, you can see the specific, and quite variable, rates used in the eight cycles of the LSKY protocol:
- Slow Breaths (SB): The rate ranges from 11-16 BPM.
- Medium Breaths (MB): The rate varies significantly, from 28-39 BPM.
- Fast Breaths (FB): The rate becomes extremely rapid, ranging from 80 to over 100 BPM.
This oscillation through different frequencies is hypothesized to be a form of "exercise" for the autonomic nervous system, challenging its ability to adapt and respond.
Part 4: Integration and Rest
The practice concludes with a long period of rest and integration, often guided as a form of Yog-nidra (yogic sleep). In the studied LSKY protocol, this final rest period lasts for 20 minutes, allowing the nervous system to settle and consolidate the effects of the practice.
Conclusion
You have now deconstructed the intricate architecture of Sudarshan Kriya Yoga. Far from being a single technique, it is a sophisticated sequence designed to modulate the autonomic nervous system through a carefully choreographed progression of distinct breathing patterns.
Key Takeaways for your Cheat Sheet:
- Multi-Stage Protocol: SKY is a sequence, not a single breath. The primary structure is: slow Ujjayi -> rapid Bhastrika -> Om chanting -> cyclical Kriya -> deep rest.
- Physiological Arc: The structure follows a clear physiological logic: induce parasympathetic calm (Ujjayi), followed by sympathetic activation (Bhastrika), and then a dynamic oscillation between states (the Kriya).
- Variable Parameters: The defining feature is the dramatic variation in breathing rate, from a slow 3-4 BPM during Ujjayi to a rapid 80-100+ BPM during the fast cycles of the Kriya.
- The Kriya Proper: The core of the practice is the Sudarshan Kriya itself—a form of continuous, cyclical breathing (no pauses) performed at slow, medium, and fast rhythms.
With this structural map in hand, you are now perfectly positioned for the next step. In our upcoming lesson, we will move from anatomy to effect, critically examining the clinical trials on Sudarshan Kriya. We will analyze study designs, statistical methods, and reported effect sizes for its application in treating anxiety, depression, and stress-related disorders, allowing you to form your own conclusions about its efficacy.
