Air is the major intake of our body in terms of volume. High oxygenated clean and fresh air is so essential. Breathing correctly leads to a vigorous life.
If you can synchronize your inhalation and exhalation with your mind, you are actually meditating.
And, if you can do it often and for a longer period, you will notice that you become lighter, brighter, and healthier.
Give it a try. It is an intrinsic nature gift. Experiment with it yourself and witness the breathing miracle.
