There are various paths to Samadhi.
The peace you may feel from a class is not samadhi in any way or form. Not anywhere near it actually. Samadhi is not a cool high happiness feeling. It is not from endorphins. It is not from hyperventilation from not breathing corrctly. If anyone was to actually read and study the yogic texts you would understand that there is long long process of techniques and gaining of capacity and real purification that has to be done way before there is even an inkling of the experience of results even the first level of samadhi. Plus, realistically, this stuff isn’t taught much less could it ever be experienced from a few years of going to a flow yoga class.
It is told by Lord Shiva, that this is the main method, due to its ease, of reaching Samadhi…… by the worshiping of nada. It is told by Sri Gurunatha (Gorakshanatha! Gorakshanatha, what does he know? He falls flat to the pure eternal flowing shakti bliss of Shiva Rea and her Trance Yoga Dance stuff) to be the main path due to its usefulness for those who are just ordinary people (what does ordinary people mean? the ones who are not extraordinary, hmmmmmm? What is extraordinary, and not from the materialistic western world perspective?)) who are not capable of attaining the knowledge of Reality or Truth and for those who have not done adequate studies. (sounds a bit like pretty much everyone in the West right?) It is for those who cannot block vrittis of the mind and it is very much easier than any other of the 1,250,000 other methods told by Sri Adinatha (Lord Shiva).
So here it is…. the technique. Sitting in a different asana changes everything as every detail always does, sit in siddhasana and in Shambavi Mudra. (not giving away that one) Listen to the nada always present in the sushumna nadi with only the right ear (see if you find that anywhere…. why the right ear only? What does it do? If you don’t feel prana and understand the divisions of prana and how it works, none of this will ever make any sense or open for you). Initially there will be the sound like intoxicated blackbees (no India black bees, not your version), then in time it will turn into the sound of 100 blowing flutes. Then much later the sound of a bell, then that of the steady firm deep sound of the clouds. Lastly the sound of the conch shell being blown. These sounds are ever present in the middle of sushumna nadi.
Sanmukhi mudra is also used to focus on nada after the nadis have been purified by correct practice of pranayama. That would be blocking both the ears, both the nostrils and as well the mouth with the fingers. Obviously, there is so much to these techniques as the tattwas are on each finger and should also be done in a precise manner.
There are four stages of nada. They are arambha, ghata, parichaya, and nispatti. Each method of blocking vrittis has these four stages. Arambhavashtha pierces brahmagranthi in anahata and a peticular unstruck sound of bhushananinada that originates from the void in the heart (shunya), atishunya, then mahashunya, is heard within the body. This is the release of pranavayu. If there has been proper building of pranavayu in the yogis heart then their body becomes lustrous, fragrant, and free from disease. (notice this is one of the reasons for building prana and not depleting it as the western mind does within its atichinta (excessive thinking, worry) and all the modern yoga practices do with excessive exercise and lack of understanding of actual yoga asana/prana) Remember, perspiration and breathing through the mouth is just the alarm going off that you have reached your maximal effort and anything more is imbalancing to prana.
Then the second stage is of ghatavashtha. The pranavayu that was released causes the union of apana and nada and bindu with the atma as they enter into the madhyachakra. Its location, the throat, is or was secret and this is what keeps the adharas together. With this union all kinds of sounds originate from atishunya. One must be firmly established in their asana for this and will attain great knowledge and physical beauty due to so many connections of lesser practices like that told in the Hatha Yoga Pradipika that should have been completed in prior to have this come to fruition properly. many of them are precursors to this. Notice how the mahaprana is moving. This is a huge key if you can understand any of this at all. Huge key to the entire thing.
The next is 3rd, Parichayavastha. The sound of the mardala is heard between the eyebrows and many many siddhis are achieved as a result of restraint. The mahaprana enters into the mahashunya at this stage. When the prana moves to this level there is a pleasure of bliss of self, not happiness but lack of anything, that is experienced through the vrittis of the antahkarana by making the nada as the object of concentration. With this one is freed from the imbalances of the elements in the form of the doshas and the pains arising from the……… basically one is freed from the threefold adhidaivika, adhibautika and adhyatmika. You are freed from the suffering you have create yourself thru your thoughts speech and actions of this and other lives. You create all of your suffering, every last little bit of it in every way.
The so-called happy materialistic person is constantly having to endure the threefold miseries of life, called adhidaivika, adhyatmika and adhibhautika. Actually no one can counteract these threefold miseries except the real yogi. All three may assail one at one time, or one misery may be absent and the other present. Thus the living entity is full of anxiety, fearing misery from one side or the other. The conditioned soul must be disturbed by at least one of these three miseries. There is no escape.
The fourth and final stage is nispatti avastha. It is when prana pierces the rudragranthi, prana enters into brahmarandra and reaches the seat of Lord Shiva. When this takes place the kvana sound of the vina is heard. There is no longer differentiation between observed and observer and all becomes rajayoga or sristisamhareti. In this state one can create as well as destroy like god.
The ancient text in my lap states that efforts of those that just do practices without understanding are fruitless. This is also said in the Hatha Yoga Pradipika as well as many other texts of yoga.
So nadanusadhanakam, or easier is just nada, is a pretty easy technique but takes time, lots of it. 15 minutes a day is nothing, literally nothing, meaning it won’t do anything. Try hours. Much of this stuff is kinda like warming up an engine, it takes a while. Then after that it builds over time, each time. Capacity builds over long time of practice, meaning years. Much like tuning a guitar or an instrument every time you sit to play it and only with years of practice do you ever get anywhere. Then on top of that very few ever become Jeff Beck or Andrés Segovia. You also need to take into consideration that most all people are not at the level of a stratocaster either. It is not like anyone can go to a yoga class anywhere and become Jeff Beck. Doesn’t happen. And there is no way to make oneself into a Stratocaster when you are just a cheap imitation Estaban sales package. (only guitarist are gonna get this one.) It would be like trying to change oneself from a cat to a dog and although sex change operations are avaiable, the package you are ain’t going to change. We are afterall in Kali Yuga.
another easy technique is unmani…… maybe next post.
