This is what I have started doing in the early morning when I wake up and before I go for a morning walk.I have been experiencing benefits of it too.
Sanskrit: वज्रासन; Vajra – Diamond or Thunderbolt, Asana – Pose; Pronounced as vahj-RAH-sah-na
Vajrasana is a kneeling pose, and it takes its name from the Sanskrit word Vajra (वज्), which means diamond or thunderbolt. Asana (आसन), of course, means pose. This diamond pose is also called Adamintine Pose. Usually, breathing exercises like Pranayama, Kapalabhati, and Anulon Vilom are done sitting in this position, and it is said that in doing so, the body becomes as strong as a diamond.
How To Do The Vajrasana
Kneel down, stretching your lower legs backward and keeping them together. Your big toes should cross each other.
Gently lower your body such that your buttocks are resting on your heels and your thighs on your calf muscles.
Place your hands on your knees, and set your gaze forward with your head absolutely straight.
Turn your attention to your breathing. Be fully aware of how you breathe and carefully observe as you inhale and exhale.
You could close your eyes to concentrate on your breathing and to calm your mind.
Try to stay in this position for a minimum of 5 to 10 minutes.
As a beginner, when you assume this position, it is likely that your legs might begin to pain in no time. If this happens, all you need to do is undo the asana, and stretch your legs forward. Give your ankles, knees, and calf muscles a good massage. In time, with practice, you should be able to go up to 30 minutes comfortably in this asana.
Also, beginners should work slowly and gradually on bettering the strength of the muscles in the lower back before they try to go deeper into the pose or increasing the duration. Once the lower back is strengthened, the strain on the breath is decreased. It is also important to note that if you push yourself more than your body can take, the benefits of the pose are minimized.
The Science Behind Vajrasana
The Vajrasana is a steady, firm pose, and those who assume it cannot be shaken easily. It is a meditative pose, but sitting in this pose can be quite challenging. One has to conquer the pain in the legs and the unrest in the mind to master the pose and enter a meditative state. One needs to train themselves to sit still and be willing to invest their mind in it.
The Vajrasana regulates blood circulation in the lower pelvic region. Sitting on your legs reduces the blood flow in the legs and increases it in the digestive area, therefore increasing the efficiency of the digestive system.
