Jala neti has gained popularity in the modern world due to the
tremendous benefit on sinus infections.
However, it is used in Yoga as a very powerful cleansing practice to
awaken higher states of meditation.
Jalaneti stimulates the pituitary gland in the brain. The full
importance of this gland has still not been unraveled by modern
science. However, in Yoga this has a great significance. This
stimulation through jala neti leads to the 'awakening' of the Ajna
Chakra which is responsible for many of the unknown functions of the
brain such as clairvoyance.
To understand the Ajna Chakra, close your eyes, relax and start
humming with the attention focused on the center of the forehead. The
ticklish sensation that you feel in the region behind the forehead is
the location of the Ajna Chakra.
It is this stimulation that is of great benefit in Yoga. In fact, in a
modern parallel, jala neti has been used to treat cases of
schizophrenia. This hints towards the beneficial effect of jala neti
to the 'mysterious' brain.
Jala neti is most efficiently done with a jala neti pot which explains
why ancient yogis used to travel of the neti pot at all times.
