He gave more initiations, empowerments, and teachings than any other Gelug master in Tibet. Every time he gave the Kalachakra empowerment, at least 50,000 people attended, and at times the crowd was as high as 200,000.
In later years Lamo Yongzin Rinpoche built several other monasteries and manifested many extraordinary siddhis. For instance, rainbows often appeared in the sky when he was giving a teaching, and once, while giving the Vajrayogini Empowerment in the cave of a female mountain deity, the nectar in his kapala cup began boiling spontaneously.
He passed away in 2005 at the age of 97, having the foretold the month and day seven months earlier. That morning, he did his usual practices, had breakfast, and announced simply, “Now I am going to die.” He told his assistant to go outside for half an hour. After the half hour had elapsed, the monks returned to his room and found him in the posture the Buddha had assumed at his Parinirvana.
