According to tantric teachings, there are many Chakras in the centre of our heart and throat. These Chakras and wind cannot be perceived by our naked eyes or machines, however they exist. When one is in control of these winds, all discursive thoughts lose their vitality. At present we are not in control of the operation or movement of wind, thus we are bombarded with discursive thoughts.
