Khechari follow up - nasopharanx mapping

Mapping the nasopharynx for Khechari stretching: what the tongue meets in turn (uvula, back of the throat, nasal septum) and how to follow the septum up to the sphenoid sinus, below the pituitary gland and optic chiasm. Also urges patience over months or years and warns against cutting the tongue, which Lahiri Mahasaya opposed.
