When one has been doing sutra neti for some time and the nasal-lining has been fairly hardened to bear the string rubbing across it, one would be able to do the next process of ‘gharshana neti’ also. Under this process we do not simply draw out the string through the mouth but holding each end, one outside the mouth and other in front of the nose, we thoroughly rub the nasal canal with the neti string by pulling and re-pulling its ends and then, after a few rubs, it is drawn out through the mouth. The Gharshana neti is to be done through each nostril by turns.
The Sutra-neti must be practiced under the guidance of an expert, for this is a bit of complicated practice and cannot be learnt merely by reading; and further in the absence of proper guidance, the tender linings of the nose might get adversely affected. This, however, is not, in the least, to be taken to imply that the Neti is in any sense dangerous or less important. On the contrary it represents the best, most complete, through and scientific way of nasal cleansing hitherto investigated.
Summing up the benefits of the sutra neti, the Hatha-Yoga Pradipika says:-
“This purifies the skull and makes it sight very keen. It also removes the diseases of the limbs above the shoulders.”
The Gheranda Samhita describing its benefits remarks,
“By means of Neti, one gets siddhi in Khechari Mudra. It also removes phlegmatic diseases and also gives sharpness in the sight.”
The investigation by a French medical authority also goes to confirm the true value and scientific importance of the Neti process already known to the Yogis thousands of years back. Thus “the dilation of the nasal passages by passing from nostrils to the throat a succession of probes of gradually increasing dimensions as an effective cure for deafness, headache, asthma and snoring, sinus, eyesight etc., was hailed by the French Academy of medicine as a marvelous research; and its inventor Dr. Glorger Gantier computes that about 70% of the people in this world stand in need of this method.”*
The sutra neti is literally a panacea for the diseases resulting from cold and catarrh:-
- In the first place it cleanses the nasal passage so thoroughly which is not possible for the water net to do owing to the sticky nature of the mucous.
- It gives a regular massage to the inner muscles of the nose and thus by toning their strength makes them proof against falling victims to germ attacks and climatic changes.
- By stimulating the nerve endings, it benefits the eyesight, the senses of hearing, smelling and tasting.
- The neti string passes in close proximity to the tonsils and over the adenoids. It is therefore ensured that a neti doer will never have to suffer from the enlargement of either of them.
- The clean nose, the healthy adenoids and the healthy tonsils result in regular and easy breathing, proper supply of oxygen to the body, harmonious functioning of the heart, good stomach, strong lungs, sharp brain, acute vision, perfect health and happy mind.
