 There is a asana, a yogic posture which is called as Sastang. The significance of this posture is that you touch eight points of your body to the ground and hold it there. In this posture, the lung, particularly the lung functions in a certain way, there are various aspects to it, but we are talking about enhancing oxygen levels in the system. The entire pulmonary system functions in a unique way in this asana. This is one of the most common asanas which has gotten distorted in many ways in common use, where almost every devotee is supposed to go into this posture, but due to lack of instruction and understanding, people are just lying down on the ground. Here is a proper demonstration of Sastang or touching eight points of your body to the ground, holding it that way and breathing slightly deeper than normal. Here the forehead, chest, two hands, two knees and the big toes are on the floor, heels together, holding it this way, the breath will naturally become in a slightly exaggerated way. Hold it that way if possible, six to seven minutes, otherwise start with three minutes. After you have done this for six to seven minutes, relax your body so that the entire body touches the floor and get into what is called as Makarasana. If you are a male person, keep right hand and top of the left hand. If you are a woman, keep left hand and top of the right hand, put your forehead and top of it and just let your body relax for three to four minutes. And then move your right leg in such a way that it is… the thigh is at right angles to the body and below the knee is also at right angles to the thigh part of your leg and turn your head to the right. Eyes closed, normal breathing and relax into this posture for three to four minutes and do the same on the other side. Turn your head to the left side, get your left leg into that posture where it is almost like you're sitting on a chair. That is, your thigh is at right angles to the rest of the body and below the knee, the shin and the calf muscle is also at right angles to the thigh and your head is looking towards the left, placed upon your palms and relax into this posture for three to four minutes and once again, go into Sarshtang for six to seven minutes. You can do a cycle like this three times at a time and you can do it four to five times in a day, especially because most of you are wearing masks right now. The danger of decreased oxygen levels, even without infections can happen because of this. If you do this four to five times in a day, this regimen, your oxygen levels will definitely be up and follow this with Simha Kriya so that your immune system will function much better. There is substantial medical evidence today to show that it actually works like this. Many universities have invested their research into this, so don't go on debating this. Just put this into action. It is not an absolute cure or a preventive but we must understand our health is not an absolute either. Our health is a consequence of many incremental steps that we take. Please take this step at these pandemic times and ensure to whatever extent possible that you do not become a victim nor do you become a spreader. Namaskaram and thank you. Simha Kriya.
