There are two types of neti kriya:
Jala neti, which is practiced
using a neti pot filled with saline solution to cleanse the nasal
passages. In this technique, the head is tilted to the side and then
salt water is poured into a nostril and exits through the other nostril.
In a more advanced technique, the water is poured into the mouth and
snorted out the nose.
Sutra neti, in which a thread is
passed through the nostrils and out of the mouth. The yogi then holds
both ends of the string, pulling it back and forth to cleanse the
nose. The thread should be rolled cotton and is often dipped in
beeswax for easier threading. A soft rubber catheter may also be
used. Sutra neti is said to be a more effective cleansing technique
than jala neti.
