1. Get up early in the morning to answer nature's call and stay for Yogic activities. Pranayama should be done in a dry, well-ventilated room. Pranayama necessitates intense concentration and focus.
2. Clean the nostrils properly before sitting for Pranayama practice. After 10 minutes of exercise, drink a cup of milk or eat a small snack.
3. Limit the conversation, feeding, resting, socializing, and physical exertion. Take a little ghee for your rice at mealtime. This will lubricate Vayu's bowels and encourage him to travel freely downwards.
4. While doing Kumbhaka, some people curl their facial muscles. It should be stopped at all costs.
It's also a sign that they're pushing themselves to their limits. This must be done at all costs. Rechaka and Puraka cannot be controlled for such citizens.
5. Pranayama should be done right after you get out of bed and right before Japa and meditation. It will lighten the body and make meditation more enjoyable for you. You must follow a schedule that is convenient and time-efficient for you.
6. Don't jerk your body around excessively. The subconscious is often confused when the body is shaken often. Scratching the body on a regular basis is not a good idea. When doing Pranayama, Japa, and meditation, the Asana should be steady and solid as a rock.
7. Repeat Rama, Siva, Gayatri, or any other Mantra, simple number, or any other time-unit according to your inclination in all of the exercises. Pranayama is better done with Gayatri or OM. You must keep track of certain time units for Puraka, Kumbhaka, and Rechaka at first. When you do the Puraka, Kumbhaka, and Rechaka as long as you can safely do them, the time-unit and proper ratio will appear on their own. You won't need to count or hold any units until you've progressed in your practice.
By force of habit, you would be automatically established in the usual ratio.
8. You must count the number for a few days at first to see how you advance. Counting would not need to be used to distract the mind in the advanced stages. When you've completed the requisite amount, your lungs will warn you.
9. Don't do the Pranayama until you're exhausted. During and during the lesson, there must still be a sense of pleasure and exhilaration in the soul. You can feel energized and refreshed during the practice. Do not overburden yourself with laws (Niyamas).
10. Do not take a bath right after Pranayama is completed. Take a half-hour break. If you perspire during the workout, don't wash it away with a towel. With your fingertips, rub it. When you perspire, avoid exposing your body to cold draughts of air.
11. Inhale and exhale gently at all times. Create no noise at all. You may make a moderate or the lowest sound possible in Pranayamas like Bhastrika and Kapalabhati.
12. Don't plan to see results by just doing it for 2 to 3 minutes for a day or two.
In the very least, you can train for 15 minutes a day for the first few days.
It's pointless to hop from one workout to the next every day.
13. Patanjali does not place a high value on the practice of various types of Pranayama. “Exhale slowly, then inhale and hold the breath,” he says. You will develop a cool and steady mind.”
Hatha Yogins were the first to establish Pranayama as a science and to list various exercises to fit different people.
14. For a few days, a neophyte can just do Puraka and Rechaka, with no Kumbhaka.
Rechaka takes a long time to complete. Puraka and Rechaka are divided in half.
15th. “Pranayama, in its most traditional and preparatory form, can be done by anyone in any pose, sitting or walking, and it will still have benefits. Fruitification would be swift for those who do it according to the recommended methods.”
16. Gradually lengthen the Kumbhaka time. Retain for 4 seconds the first week, 8 seconds the second week, 12 seconds the third week, and so on before you can hold your breath to your maximum potential.
17. You must change the Puraka, Kumbhaka, and Rechaka in such a way that you do not feel suffocated or uncomfortable at any point of Pranayama. Between any two consecutive rounds, you should never feel compelled to take a few regular breaths. Puraka, Kumbhaka, and Rechaka must all have their durations adjusted properly. Take extra precautions and pay close attention. Things will turn out to be good and straightforward.
18. Exhalation should not be prolonged if it is not necessary. If you take longer to perform Rechaka, the next inhalation will be rushed and the flow will be disrupted. You must be able to control the Puraka, Kumbhaka, and Rechaka in such a way that you can do not only one Pranayama but the entire course or necessary rounds of Pranayama with utter comfort and care. This is what I have to say over and over again. Perfectionism is attained through practice and experience. Maintain your composure. Another critical aspect is that at the end of Kumbhaka, you must have good control of the lungs in order to perform the Rechaka smoothly and in proportion to the Puraka.
