Ngakso is a profound method of purifying the Vajrayana vows, which was hidden by Padmasambhava as a terma for the benefit of future generations with the prediction that it would greatly benefit beings. Terton Chokgyur Lingpa rediscovered these teachings and received direct instructions from the Lotus-born himself when he appeared to him in a vision. Therefore, the perfect oral instructions of this practice are not distorted. Now all the lucky ones with good karma have the opportunity to join this great practice under the guidance of a recognized master. It is said that even those who do not practice will gain attainment of the blessing of achievement.
