Details of sūtra neti: the thread (sūtra) is lubricated with sneha (generally ghee or oil) to facilitate passage. It should be “firm” (gāḍha) — neither too rigid nor too flexible.

The thread is inserted through one nostril and comes out through the other (or through the mouth in advanced variants), cleaning the nasal passages of mucus and allergens.

This practice, though initially challenging, becomes comfortable with regular practice and offers significant respiratory benefits.
