The importance of this opening is unique. The gate always remains closed and a common person knows nothing about it. Only the Yogis understand its importance and they also know the method to open it. When a Yogi awakens the Kundalini and raises the prana up to this opening, it is the final destination. If one opens it and leaves the body by discharging prana through this opening, one gets to Kevalya or moksha (the union with the absolute). Only the great Yogis can leave the body this way and achieve the ultimate aim of life (moksha). All the rest give up life through other openings.
