Close your right nostril with the thumb of your right hand after sitting in a relaxed posture. Inhale through your left nostril for ten seconds. Hold your breath for 20 seconds after closing the left nostril with the small finger of the right hand. After 20 seconds remove the thumb from the right nostril and exhale through it for 10 seconds. Now inhale through the same nostril for 10 seconds and hold your breath for 20 seconds by closing it with the thumb. Exhale through the left nostril for 10 seconds after removing the small finger. This makes it one cycle. Complete 10 such cycles. This exercise is also done once in the morning and once in the evening before going to bed. This exercise would yield the best results if it is done on an empty stomach in an open and airy place.
All those students who are practicing these exercises are advised to have their dinner early in the evening. There must be a gap of at least three hours between dinner and the exercise i.e. the exercise should be done three hours after taking the meal.
After this breathing exercise, sit in such a posture when the muscles are relaxed. Imagine with closed eyes that there is a ball which is filled with lights of blue color and these lights are falling on you from that ball. These lights after absorbing in your brain and circulating through your whole body are being earthed through your feet.
Absorption in this exercise and depth in imagination will give you a sense of lightness, so much so that the action of gravitational pull will appear to come to an end.
After having perfection in this imagination this exercise is required to be done with open eyes. You are required to witness that you and this world of yours are encased in a ball which is filled with blue lights, on completion of this exercise one starts feeling so light that when he walks he feels as if he is walking in the air.
During the course of this exercise, this caution is also to be exercised that when you are walking on the roadside please do not attempt to practice it. Because the sense of liberation from gravity could result in losing contact with the ground. If this state ever overpowers you automatically, when you are walking on the road, get aside and walk on footpaths only by keeping your feet firmly on the ground so that you may not be bumping into someone. This practice, however, can be done at home. There is no harm in doing it within the four walls of the house.
