Let’s see what Hatha Yoga Pradipika (HYP), classic fifteenth-century Sanskrit manual on hatha yoga, says on Kapalabhati and Bhastrika.
What is Kapalbhati & its History?
First we discuss about Kapalabhati. Let us break this word into two words. First word is ‘Kapala’ which means skull (head) and another word ‘bhati’ which means shining. It means that practice of this pranayama shines the forehead. HYP does not call this practice as pranayama, but it treats this exercise as one of the six cleansing actions.

In the above sloka, Hatha Yoga Pradipika has defined six types of detoxification (cleansing) actions called Shatkarmas These are: Dhauti, Basti, Neti, Trâtaka, Nauti and Kapâla Bhâti. Kapalabhati is one of purification exercise.

How Kapalbhati is Practiced?
Let us understand the technique of doing this kapalabhati.
- First sit comfortably in any meditative posture - padmasana or vajrasana. Always keep your back straight.
- Take 2 or 3 deep breathings before starting kapalbhati.
- Forcefully exhale from the abdomen quickly and repeatedly. Just keep focus on forceful exhalations (this is called active exhalation). Inhalations will spontaneously occur after every exhalation (this is called passive inhalation).
- Gradually, increase the frequency of forceful exhalations to about 20-30 per minute initially. You can increase the frequency up to 60 strokes per minute. This is called one round.
- At end of a round, slowly and exhale the remaining breath if any inside the lungs . After this, normalize your breath and relax.
For 2nd round, again start from step 3 and continue to step 6.
The keypoint here in this practice is forceful exhalations using abdominal muscles (and not chest muscles). You should practice this only within your capacity and comfort level.
At end of this practice, there is temporary suspension of breath and then there is a feeling of tranquility and peaceful silence. This spontaneous pause of breath is kumbhaka.
Benefits of Kapalbhati
Physiologically, this practice has cleansing effects on the lungs. It is a good practice for respiratory disorders. It helps cleans the capillaries of the even remotest part of the body. It cleanses the nasal passages. Abdominal muscles and digestive organs are toned. If you are feeling a sort of laziness or fatigue, or sleepiness, this will help you.
Oxygen and energy levels are enhanced by the practice of kapalabhati.
Precautions during Kapalbhati
But be careful as this is a vigorous breathing technique. So, come back before your muscles and lungs are tired.
(Precaution - If you have low back pain, or any surgery in the abdomen, or if you suffer frequently from high blood pressure, heart problem, do not practice it).

What is Bhastrika and its History?
Coming to bhastrika pranayama (Bellows Breath), let’s see what Hatha Yoga Pradipika says on it.
अथ भस्त्रिका
ऊर्वोरुपरि संस्थाप्य शुभे पाद-तले उभे |
पद्मासनं भवेदेतत्सर्व-पाप-परणाशनम || ५९ ||
atha bhastrikā
ūrvorupari saṃsthāpya śubhe pāda-tale ubhe |
padmāsanaṃ bhavedetatsarva-pāpa-praṇāśanam || 59 ||
This shloka suggests padmasana for bhastrika pranayama. One can also sit in sukhasana or vajrasana for bhastrika pranayama. The requirement is to have stable posture.
यथोदरं भवेत्पूर्णमनिलेन तथा लघु |
धारयेन्नासिकां मध्या-तर्जनीभ्यां विना दॄढम || ६४ ||
yathodaraṃ bhavetpūrṇamanilena tathā laghu |
dhārayennāsikāṃ madhyā-tarjanībhyāṃ vinā dṝḍham || 64 ||
Hatha Yoga Pradipika has suggested bhastrika pranayama to be practiced in such a way that the air should be drawn in through the right nostril by pressing the thumb against the left side of the nose, so as to close the left nostril; and when filled to the full, it should be closed with the fourth finger (the one next to the little finger) and kept confined.
How is Bhastrika Practiced?
But here, we will discuss the simple bhastrika.
Bhastrika means bellows of the blacksmith. Like bellows, inhalations and exhalations are done rapidly. Remember in kapalbhati, we focused on rapid exhalations only. So, in bhastrika pranayama, inhalations and exhalations are performed again and again quickly and with force.
Now, let’s understand the technique.
- Sit in comfortable meditation posture with the hands resting on the knees in gyan mudra.
- Keep the head and spine straight, close the eyes and relax the whole body.
- Take a deep breath in forcefully through the nose. Immediately afterwards, breathe in with the same force. Forceful inhalation results from fully expanding the abdominal muscles and forceful exhalation from firm contraction of the abdominal muscles. Do not strain.
- During inhalation, move the abdomen outward. During exhalation, move the abdomen inward. This movement should be slightly exaggerated.
- Continue in this manner, counting 10 breaths.
- Take a deep breath in and breath out slowly.
- This is one round. Practice up to 5 rounds. When adjusted to this style of breathing, slowly increase the speed, always keeping the breath rhythmical. The force of inhalation and exhalation must be equal.
Benefits of Bhastrika Pranayama
- This practice burns up toxins and helps balance the vata pita and kapha doshas or humours in our body.
- Because of the rapid exchange of air in the lungs during this practice, there is an increase in the exchange of oxygen and carbon dioxide into and out of blood stream. This stimulates the metabolic rate, producing heat and flushing out wastes and toxins. This is helpful for overweight people therefore.
- The rapid and rhythmic movement of the diaphragm also massages and stimulates the visceral organs, toning the digestive system.
- Bhastrika reduces the level of carbon dioxide in the blood. It helps to alleviate inflammation in the throat and any accumulation of phlegm. It balances and strengthens the nervous system, inducing peace, bliss/tranquility and concentration of mind in preparation for meditation.
Precautions During Bhastrika Pranayama
Bhastrika Pranayama is hyper ventilation technique. So, in case, there is a sense of suffocation at any stage of this pranayama, stop the practice and consult the yoga expert/teacher.
If you have high blood pressure, insomnia, mental or emotional disturbance, do not do this practice.
