 Bringing a balance between Eda and Pingala is a very important part of living a balanced life. Forty minutes at a time, four times during the day, there is a certain transition happening. These are called twilight zones or sandyas because at this time the balance between Eda and Pingala shifts very rapidly. In the yogic way of looking at things, there is no such thing as body and mind. There is physical body, there is mental body, there's energy body. The energy body comprises of seventy to thousand nadis. When we say a nadi, it means a channel or a pathway. Nadi does not mean a nerve. If you cut open this body, you will not see the nadis. There is no such thing physically. But experientially if you observe the nature of the movement of energy in the system, you will see that it always moves along established pathways never randomly. So there are seventy to thousand ways in which it moves. Thirty-six on the right, thirty-six on the left, thirty-six thousand on either side. The right is called as Pingala. The left is referred to as Eda. These are also referred to as sun and moon. So these two, Eda and Pingala or the sun and the moon, the right and the left on the level of your mind signify the logical and the intuitive. When I say intuitive, intuition is not another dimension of perception, but just another dimension of computing. If you have the same amount of information within you, if you go logically, there may be ten steps to get to a place. Intuition means you don't take the ten steps, you just jump to the tenth step. But today modern education systems, one hundred percent stomping on the intuitive dimension, only the logical is developed. Anything intuitive is dismissed off as Mumbajumbo for everything you have to think through. What your grandmother's just knew, today you have to do a billion-dollar research to find the same thing. When you have to think through everything and everything seems to have multiple steps, now life becomes stressful. If one wants to be successful beyond a certain point, there are some things where you should be able to jump the steps and arrive at it. Still the same information, still the same stuff, it is just that you don't have to walk through that many steps every time. This makes life very stressful because it is like you're driving your car on two wheels. The other two wheels unused and safe. I don't know for when to be used, but the two wheels that you're using will feel enormous amount of stress. So in the yogic system, the significance of the intuition is as important as the logical. So bringing a balance between Eda and Pingala is a very important part of living a balanced life. Being able to conduct yourself through complex situations with ease comes only when the intuitive dimension of your mind is sufficiently evolved and developed. Otherwise small things will freak you because for everything there are multiple steps. Here we'll be doing a few things to bring a balance between Eda and Pingala to give you an experiential understanding of this. If you take your forefinger, place it beneath your nostrils and gently exhale. Find out in which nostril the breath is dominant right now. How many of you right? Left. Okay, it's either right or left. Only two barrels, you know. If there were twenty-five, how complex it would have been. If you observe yourself through the day, you would have noticed that approximately between forty to forty-eight minutes the dominance of the breath will shift from right to left and left to right. Have you ever noticed this? Have you? Why this is happening is within the system the dominance of energy, a prana which is the vital force in the system is shifting from Pingala to Eda and Eda to Pingala every forty minutes. Once the energy shifts, within the next eight minutes the breath will shift. If you're in a perfect state of health and well-being it will shift within a few minutes or we can say instantaneously. This shifting is happening every forty minutes but during certain times of the day, which are referred to as the Sandhya Kalas, which means the twilight zones, twenty minutes before sunrise, twenty minutes after sunrise. Oh, that's okay, Sadhguru. Tell me if there are other times. Twenty minutes before noon, twenty minutes after noon, twenty minutes before sunset, twenty minutes after sunset, twenty minutes before midnight and twenty minutes after midnight. Forty minutes at a time, four times during the day. There is a certain transition happening. These are called twilight zones or Sandhyas because at this time the balance between Eda and Pingala shifts very rapidly because it's shifting rapidly within yourself. It's very easy to bring it to a balance at these times. To an extent, almost everywhere in the world, anything, any spiritual process or practice means morning, evening. Sandhya has become synonymous with spiritual practice. The time has become synonymous with many practices. So bringing a balance between Eda and Pingala is important for a balanced development of a human being. You feel truly comfortable only when you're in balance in some way. There's any kind of imbalance, there's discomfort, isn't it? Yes? When you're experiencing any kind of imbalance, there is discomfort. Only when you attain to a certain balance, you feel really comfortable. So comfort is never really determined by what you're sitting on or where you are. Comfort is determined by how balanced you are within yourself. This basic comfort that every human being must have, unfortunately, has been denied to too many people. Just to sit with total ease in one place is not there in most people right now, isn't it? Simply sitting in ease, complete ease, it is not there. So when there is no ease, it's a disease, whether you're medically diagnosed or not, it is a disease. If the disease continues over a period of time, it will manifest itself in the body as a malfunction, which gets labeled as some kind of disease, like incredible names they're coming out with, for every kind of problem. The fundamental reason why the system doesn't last its span, it's designed to last its span, but it is not lasting its span because we're keeping it in various levels of imbalance. You drive your car in just two wheels all the time, you know, something will break down. So similarly the whole system is not being properly kept, there is not enough balance in the system. Only when you're in balance there is comfort, otherwise there is no comfort, one will not know comfort unless he knows some sense of balance within himself. Only when you're in balance you can be still and man is ill. Human beings are ill only because they do not know how to be still. Stillness will not come unless there is proper balance. Only when you're totally balanced you can be still within yourself, otherwise that will not happen.
