The lineage of Vajrakilaya begins with Vajrakilaya himself teaching it to the Five Buddha Families and Dakini Dewai Khorlo in Akinishta heaven. Later on Dakini Dewai Khorlo transmitted it to the Mahasiddha Prabhahasti, one of the eight Vidyadharas who holds the eight oral transmissions called Kagye. He, in turn, transmitted it to Guru Rinpoche who, once he had realized the nature of Vajrakilaya, transmitted it in Tibet. He hid much of it as a treasure for future generations. Later on according to the prophecy of Guru Rinpoche and other great tertons, His Holiness Dudjom Rinpoche then revealed this terma for the benefit of our generation. The blessing of the oral lineage of Kama and the Treasure Lineage of Terma is fully intact; because of that it is very sharp, swift, and effective.
His Holiness Dudjom Rinpoche, Jigdral Yeshe Dorje (1904-1987), received this teaching in a dream when he was 34 years old. In the dream, Yeshe Tsogyal came to him carrying a small sky-metal phurba, which had been given to her by Guru Rinpoche after he had transformed into Dorje Drolo and subjugated the eight classes of spirits. His Holiness took the phurba to receive empowerment from it, and thus placed it on his three centers. When he touched it to his heart center, he instantly transformed into Vajrakilaya with his lower body in the form of a phurba dagger. With this Yeshe Tsogyal was very pleased and told him that this was the correct way to take the initiation and reminded him that they had received this transmission together from Guru Rinpoche. She then told him to guard the phurba carefully and shook his hand. With that, His Holiness woke up and remembered all the teachings of Vajrakilaya that he had received from Guru Rinpoche, but he decided to write down only the very essence of it and these are the teachings and practices of the Putri Rekpung.
