Roll your tongue upwards and pull it in so that it comes to rest against the tonsils. Usually, our tongue is tied to the lower jaw with a thin but strong nerve. Hence, lolling out or rolling in of the tongue is difficult. To facilitate the process, this connection is cut first. A sharp blade of diamond or other crystal is used to cut this nerve. The process is not painful simply rub the nerve four or five times daily with this blade. Thus, in a few days, the nerve is cut, then slowly continue to cut the remaining connection of the tongue with the jaw up to the base of the tongue.

With continuous practice, your tongue will be so long that it will reach up to junction of eyebrows. This posture is very helpful in attaining complete meditation.
