About Black Hayagriva, by Lama Sonam Tsering Rinpoche:
"The emanation of all Buddha’s speech arises as Avalokiteshvara, the form of compassion. In order to tame the wildest beings, Avalokiteshvara manifests as extremely wrathful Hayagriva. In this time of degeneration the inner elements of beings are imbalanced with very strong clinging and passions. Externally, this causes war and the use of biological and chemical weapons. Many new diseases with no known cure appear and epidemics spread quickly. Even friends, husbands, wives, and children seem intent on cheating and manipulating each other, so that no one knows who to rely on. This naturally leads to imbalances in the outer elements. The water element causes floods, tsunamis, and hurricanes; the fire element causes volcanoes, drought, and heat waves; wind causes tornadoes and windstorms; and the earth element causes earthquakes and landslides. Likewise, all the different classes of spirits become upset. The whole world, whether it is the inner elements of sentient beings or the outer elements, is extremely turbulent and out of control. At times such as this it is difficult for Buddhas, Bodhisattvas and wrathful deities to penetrate beings’ minds. That is when this form of Hayagriva in union with Tröma Nagmo, who is the most wrathful and therefore the most compassionate, appears.
"Extremely Wrathful Black Hayagriva has special power to affect beings’ minds and benefit those who are depressed, dysfunctional, or crazy, as well as to cure disease. This is the condensed essence of all the billions of Hayagriva practices. It is easy to practice and highly effective. Even hearing this practiced will subdue all classes of spirits. Remembering it will eradicate all wrong views and demonic forces. Touching the image of this Hayagriva will pacify all disease and the passions of the five poisons. For whoever has a connection to this practice the seed of samsara will be destroyed.
"Padmasambhava accomplished deathlessness through practicing Hayagriva. He transmitted it to his heart disciples, Yeshe Tshogyal and King Trisong Deutsen to practice and hide as terma. This terma was later discovered by Dudjom Lingpa, who was the emanation of Khyeuchung Lotsawa and Guru Dorje Drolod in person. HH Dudjom Rinpoche compiled this whole practice to make it easy to practice."
