Bandh is a special characteristic of Hatha Yoga. The various types of
bandhas have been described in Yoga texts. However none of them defines
the term "Bandh" as such. The three types of bandhas, viz Jalandhar Bandh,
Uddiyan Bandh and Mul Bandh have been described in many of the ancient
texts. With the help of these descriptions, an attempt may be made to
define the bandhas. Bandh may be defined as a particular action involving
pressure or strain on the muscles. It is expected in Yoga to retain a
firm pose in bandh as it is retained in the asanas.
Kapalbhati (Frontal Lobe Cleansing)
'kapalbhati' is one of the 'shatkarma' which has been mentioned in the 'Gherand
Samhita' & 'Hatha Yoga Pradipika'. The literal meaning of 'kapal' is
cranium and 'bhati' is light or shining. So kapalbhati means increasing
the efficiency of the organs situated in the cranium. So we can say that
kapalbhati improves the function of brain. Another name for kapalbhati is
In processes of kapalbhati exhalation is fast and with jerk while
inhalation is slow, passive and without any efforts. Emphasis is given
more on the processes of exhalation.
In natural respiration emphasis is on inhalation, it is active and
exhalation is passive. In kapalbhati the processes is exactly reversed,
giving more importance to exhalation and less importance to inhalation.
About the benefits of kapalbhati it can be said that it helps to clear
and purify the mucus, dust, carbon particles from the respiratory tract.
Physiologically during natural respiration the cerebro-spinal-fluid
around the brain is compressed and decompressed. This happens 14 times a
minute, the natural respiratory rate. In kapalbhati the exhalation is
with jerk and inhalation is passive, so the compression? decompression
effect is enhanced. Further the process is fast, 120 times a minute which
increases the effect. Because of this the brain is being massaged which
will improve the blood supply to the brain and increase the function of
The circulatory system is also affected by contraction and relaxation of
diaphragm and the abdominal muscles. While exhaling the blood from
abdominal region is pushed towards heart. During inhalation the venous
return from legs to abdomen increases and in next round same blood is
pushed towards the heart. So kapalbhati improves venous return to the
heart and helps to improve circulation.
Apart from above mentioned benefits, kapalbhati helps to improve
digestion, the function of liver and pancreas. It also increases the
strength of abdominal muscle and the diaphragm.
