Kundalini Yoga’s Ida-Pingla as the erectus spinae muscle and Sushumna Nadi as the spinal cord

Friends, many times I feel that some important thing is being hidden or is not being discovered. It is being said that Naadis are subtle pathways which have no physical existence, but this is not possible. Whatever experience you take, it definitely has a corresponding physical existence. No matter how subtle any emotion, behavior, thinking, etc. are, they definitely have a physical form in the brain or body. Without physical expression there is only a bodyless soul. However, it also contains coded data of physical experiences of past lives in subtle or latent form. Then when a line of light is felt in the Sushumna, it must definitely have some corresponding physical form that generates it. It is the spinal chord. I think that the erectus spinae muscles that run from the sacrum to the skull, on either side of the spine, provide physical expression to ida and pingala. However, such a rope-like muscle can be felt only when touched, especially in the lower part of the body up to the sacrum. Generally, one feels a upward surge of energy or enthusiasm in some left or right part of the body, like yawning. It seems as if it is disappearing into the sink of Ajnachakra point. The skin on the forehead or face seems to be pulled in the direction in which the energy is flowing.When I touch these two main muscle bands, they feel like tight ropes. Both sides of the spinae muscle sometimes become tight and sometimes loose. When it is tight, mainly happening with muladhara tucking, it seems that some inner pleasure sensation has gone up through it and due to this the energy pressure of the perineal organ has reduced. Looking at the anatomy, they are spread out in the back just like I feel. These begin around the sacrum. First they are a little less wide, while going up, they are less spread at the level of the navel and are wider at the level of the heart and become less wide at the base of the skull and get connected to the skull by turning on both sides. Science also says that just as chemical sensation flows in the nerves, it also flows in the muscles. It may be that it flows faster in or easier in the muscles, that is why the sensation of the perineum does not go through the spinal cord and passes through these two muscles which are called Ida and Pingala. You imagine that there are three parallel pipes. There is a thin pipe in the middle and a thick pipe on either side. If you leave the left pipe completely open and close the right pipe completely, all the water will pass through the left pipe. If you leave the right pipe completely open and close the left pipe completely, all the water will pass through the right pipe. If you leave both of them half open then the excess water will flow towards the other side pipe and during this time it will also pass through the middle pipe. Only the remaining water will reach the other pipe. Perhaps the same thing happens when Ida and Pingala are activated together. Meaning, the sensation also starts flowing through the Sushumna. Both the pipes cannot be kept fully open simultaneously because there is not that much water. Meaning, the more you close one nadi, the more the other nadi will open. I feel that when the sensation of the perineum goes up, sometimes the stretched muscle on the left side becomes taut and feels like a rope and sometimes the one on the right side. When both are equally and lightly stretched, it seems as if some sensation goes up through inside the spinal cord too. That’s why then one feels a different and special balanced bliss and freshness.
