Zong Rinpoche was one of the foremost Lamas of his generation, and a life-long Dorje Shugden practitioner besides…
“(Zong) Rinpoche was born in Kham in 1905. He went to Lhasa when he was eleven years old to study at Shartse. He studied effortlessly and became renowned as a powerful and irrefutable debater. A learned geshe at that time said that ‘even if Shri Dharmakirti had been present, he would not have been able to debate better than that.’
After graduating as a high ranking Lharampa geshe at the age of twenty-five he moved on to the Tantric College of Gyuto. In 1937 he was appointed abbot of Shartse, a position he held for nine years.
Rinpoche was known as a strong, detached and wrathful lama. He had impeccable knowledge of all rituals, art and science, and he never hesitated to give reasons to others why this action or that painting was wrong.
He was renowned for his ‘many actions of powerful magic,’ as a result of which ‘the most marvellous, indescribable signs occurred.’”
-Wisdom: Magazine of the FPMT, Number 2, 1984
“In 1916 ( Zong Rinpoche) went to Lhasa to study the dharma at Shartse college (of Ganden Monastery), where he studied the sutras of the Prajnaparamita, Madhyamika, the Abidharma and the Vinaya. He quickly became famous as a sharp analyst and master of philosophical debate. In 1929 he successfully completed his geshe examinations and was awarded with the highest degree, the Geshe Lharampa title …. in 1937 he became abbot of the Shartse college.
So his name spread all over the country of being a powerful tantrika and he gave many empowerments and teachings on those subjects with a special emphasis on the tantras of Heruka, Hayagriva, Yamantaka, Gyelchen Shugden, Guhyasamaja, Vajrayogini, Green Tara, Mahakali, White Tara, Vaishravani and others. …
He was one of the last teachers of the old generation with the aura of authority and a kind of aristrocratic touch or vajra pride. In his teachings he followed very strictly the original texts. But, concerning his age, he was very open and patient to us Westerners, always kind, polite and helpful to answer our many questions concerning detailed tantra explanations.”
