A disease-free system should be the starting ground for yogasanas and pranayama. There are six specific cleansing techniques, known as Shat Kriyas, which eliminate impurities and help cure many ailments.

Jalaneti:

Most diseases of the nose and thraot are caused by the accumulation of impurities in the nasal passage. Jalaneti is a process of cleansing the air passage of the nostrils and the throat by washing them with tepid saline water.

Take a clean jalaneti pot. Put half a teaspoonful of salt in the pot and fill it with lukewarm drinking water. Stand up and tilt your head slightly to the right. Insert the nozzle of the pot in the left nostril and let the water flow into it. Inhale and exhale through the mouth, allowing the water to flow out through the right nostril. Reverse this process by tilting your head to the left and letting the water flow from the right to the left nostril.

Jalaneti should be practised only in the morning. It will relieve sore throat, cold, cough, sinusitis, migraine, headache and cases of inflammation of the nasal membranes. It keeps the head cool and improves vision.
