“Likewise, Lama Trijang Dorjechang, Junior Tutor to His Holiness the present Dalai Lama, folds his hands upon the crown of his head whenever he mentions Kyabje Pabongka Rinpoche. He was such a great lama, unsurpassed by any, that hardly any lamas or geshes of the Three Pillars (the monasteries of Ganden, Sera and Drepung) had not been his disciples.
Once, in the “cave-under-water,” he experienced a manifestation of Yamantaka for nine days, while he himself was essentially Heruka Chakrasambhava. Further, he experienced a manifestation of Vajrayogini who told him of the benefits to be derived from merging the Vajrayogini teachings of the Sakya and Gelug traditions into one meditational practice. When he once made a great tsog offering beside a Heruka statue in Lhasa, the wisdom body actually entered into the statue. The statue danced and told him that whoever received Heruka initiation from him up to the seventh generatoion would be taken to the dakini realms.”
