Drupchen Khepa Nyima Bum
Drupchen Khepa Nyima Bum (Wyl. sgrub chen mkhas pa nyi ma 'bum) (1158-1213) was an important lineage master of the Nyingtik teachings. According to a prophecy in the Reverberation of Sound Tantra, he was considered an emanation of Vajrapani.
Nyima Bum was born to Shyangtön Tashi Dorje. While he was in the womb, his mother dreamed of many suns rising at once. She related the dream to her husband, who said, "This is a sign that the child will serve the teachings of the unsurpassable secret and dispel the darkness of ignorance for countless beings." He named the child Nyima Bum ('A Hundred Thousand Sons'). Between the ages of five and nine, the boy was taught by his father, who gave him all of the empowerments, teachings, and instructions of the secret Nyingtik cycles, like one vase filling another. At a ceremony of enthronement when he was ten, he astonished all of the students present by giving a discourse on the seventeen tantras, the principles of which he practised assiduously and exclusively until he was twenty. At the age of twenty, after his father had passed away, Nyima Bum went to study with Gyaltsa of the Ngok clan and became learned in many tantras of the Sarma schools and the instructions associated with these.
Drupchen Khepa Nyima Bum transmitted the complete lineage of empowerments, teachings, and instructions of the secret Nyingtik cycles to his nephew, Guru Jober.
