I was reading the original sentences of some great Yogis filled with their experiences. Actually they used to keep them secret in diaries. These diaries used to reach their relatives only after their death. It is better not to reveal the names of great Yogis. Because otherwise, one can be accused of disrespect. They are revered by countless people. The feelings of those people can also be hurt. The staunch supporters of great people can get angry with the review of their statements etc. Similarly, no one wants to hear anything bitter about his culture, religion, nature etc., even if it is the truth. The writer needs to be very careful. Controversial issues should be said in gestures only. This kills the snake and the stick also does not break.
The main points that I came to know were the following. The breath stopped, the breath went inside, the breath started going in reverse direction, and there was a heaviness in the brain, the breath went inside the Sushumna. These can also be called the keywords of yoga. You can make as many Kriya yoga exercises from this as you want. But they are of little use. Because Pranayama is basically the same, which works. This is the reverse breathing or the breathing inside. In my opinion, this is what is called the breathing inside or the stopping of the breath. Actually, the breath of a living being cannot stop. It is possible that by practising reverse breathing, such a situation comes that the breath becomes so slow and light that it cannot be felt. But this can happen only with reverse breathing, not with straight breathing. It is with reverse breathing that the mind stops. Because the mind considers straight breathing as breath. Reverse breathing is not breath at all for it. This goes on like a chain reaction. When the mind stops, the breath will become even slower. Of course, the reverse will continue. With the mind stopping, a stage will come when the breath will become almost unnoticed. It will not be an exaggeration to call such a state the realization of the soul or the Brahma or very near to it. Pranayam is not just breathing, but breathing in the right manner is Pranayam. While inhaling, the energy should be felt rising through the back, and while exhaling, it should be felt going down. This happens on its own, because while inhaling from the stomach, the energy rises from the Mooladhar and reaches the pit of the Manipur Chakra. Then from there it rises upwards with pulling the chest and back upwards. As soon as the back and chest are pulled upwards, the energy of the spine is also pulled upwards by itself. By casting a little glance upwards between the eyebrows, it gets pushed even more upwards. And the energy gets aligned straight in the Sushumna line, from the muladhar Chakra to the agya Chakra. Sometimes it comes to the Agya Chakra through the Sahasrar, and sometimes it bypasses the Sahasrar and goes straight to the Agya Chakra.
The words of old Yogis like “pulling the breath, the breath went up to the head”, eye went up (means upward gazing of agya chakra), tongue went up (means tongue’s back touched back palate) etc. show that Pranayam is a science of pulling, not of relaxation. Of course, when the head becomes very heavy or the head starts aching, then do not pull like this. When the head becomes light, then start pulling again. I myself have felt that after this heaviness of the mind, a very creative, emotional, practical and divine power comes. All human and divine qualities come automatically. The feeling of detachment and non-duality arises automatically. It seems that nature is helping everywhere like a servant. Yogis also say the same. But what I say clearly, and what Yogis have been shying away from saying, is that this is only the sexual power, nothing else. This sexual power rises only with the Pranayam done correctly. If sexual intercourse is done correctly, then artificial Pranayam is dwarfed in front of it. Of course, only the combination of both can provide complete and permanent benefits. Although complete benefits can be obtained even by just Pranayama. But it may take more time for the practice to mature. We have been habituated to straight breathing since many births. That is why it is not so easy to form the habit of reverse breathing. Reverse breathing means that the focus is not on the inflow of air, but on the rise and fall of energy in the back. The descent of energy will be considered automatically, when the back will descend on its own while exhaling and will become relaxed. It is called reverse breathing because in this, when the energy is rising up in the body, at that time the breath or air is going down in the body. And when the energy is descending in the body, at that time the air in the body is rising up to come out.
The energy is pulled more only when you breathe from both the stomach and the chest. Of course, it should be done very slowly. A good Pranayama may take up to 1 minute. For example, first stop for a while when the belly area becomes full of air. Then apply the second level of pull by raising the chest. Then pause for a while and the pull of the third level is felt by looking upwards at the Agya Chakra. There is a feeling of touch an upward gushing like gharrrrr and the heaviness of the brain increasing with it. After this heaviness, new and old thoughts surge in the soul like air bubbles in the air. There is a great pleasure. Yogis have written it like this, bada maza aaya, maza bhayo etc.
There is a water wheel to draw water from the well. A bucket is tied to a rope. That rope rests on a pulley. The other end of the rope is in the hands of a man. When the man pulls the rope, the bucket end of the rope goes up and also lifts the bucket filled with water from the well up. When the man loosens the rope, the bucket end of the rope goes down into the well and takes the empty bucket inside the well. Breath also works like this rope and Kundalini Shakti works like a bucket. When breath is inhaled, meaning the breath string is pulled long, then with its force the Kundalini Shakti rises up in the well of the back and pours the water in the form of shakti into the brain. When breath is exhaled, meaning the breath string is loosened and made short, then the empty Kundalini Shakti descends down the back. It then fills itself with water in the form of power in the Muladhara Chakra, and again rises up in the next breath. In this way, this manual pump of breath keeps working for the entire life. That is why breath is often compared to a string, Mooladhar to a well or a pit and Shakti to water.
This sexual power remains confined to the lower parts of the body for reproduction and remains constricted. It is said that the Kundalini Shakti is wrapped in three coils around the Shivling. That is why a snake is shown wrapped around the Shivling. All these things are interconnected. But in the real Shivling, when this Shakti-form serpent rises up to form a hood over the Shivling, then only one coil remains below. Meaning, there is so much of it in the Mooladhar. Kundalini is such a power that it cannot be destroyed in a living being. If it’s finished then creation will also be threatened to be finished as there will be no sexual desire. If all the coils open, it means that the power is about to end. But the presence of one coil always shows that the Kundalini power of Muladhara is unlimited. It means that it can continuously straighten up and keep climbing upwards. But even then a large part of it will remain contracted in Muladhara. All this cannot be merely symbolic. If it were so, then the Vam Marg tantra would not have existed. But the basic tantra is this same. All the other tantras are based on it. But it seems that all of them are engaged in rejecting their own origin.
