Yongey Mingyur Dorje Drakpo Nuden Tsal, who was born in the Lhatok region of Kham in 1628, was an extraordinary individual who embodied the wisdom and goodness of his tradition, Tibetan Buddhism, while transcending the status quo of its institutions.
In his early years he had visions of Padmasambhava, Karma Pakshi, Hayagriva, Vajra Varahi, and Mahakala and composed a guru sadhana for Karma Pakshi from a mind treasure received in a pure vision.
On one occasion the Kagyu lineage was severely weakened due to invasion, as well as outer, inner, and innermost obstacles. At that time, in accordance with Guru Rinpoche’s prediction, Yongey Mingyur Dorje revealed the complete teaching cycle of Guru Dorje Drolo which he then offered, in secret, to the Tenth Karmapa, Choying Dorje. The great terton personally practiced the approach, accomplishment, and activity applications of Dorje Drolo for nine months and by doing so vanquished the outer, inner, and innermost unfavorable circumstances and obstacles, including the invading army. Thus he caused the Karma Kagyu teachings to shine like the rising sun. (–excerpted from rangjung.com)
