Bhaduri Mahasaya performed the
Bhastrika Pranayama before me
with such amazing force that it seemed
an actual storm had arisen in the room!
Then he extinguished the thundering
breath and remained motionless
in a high state of superconsciousness.
The aura of peace after the storm was
vivid beyond forgetting.
