Some information from the following books:
“The Jewel-garland Biography of the 97th Gaden Throne Holder Kyabje Yongzin Ling Rinpoche” by the 14th Dalai Lama, Wisdom Publications
“The Magical Play of Illusion” by Trijang Rinpoche, Wisdom Publications
His Holiness The 14th Dalai Lama has received this empowerment from Ling Rinpoche sometime around in 1950 during his stay at Dromo, Tibet’s southern border between Sikkim and Bhutan.
“The Jewel-garland Biography of the 97th Gaden Throne Holder Kyabje Yongzin Ling Rinpoche”:
As preparation for my retreats on single-deity Vajrabhairava, Eleven-Face Avalokiteśvara, and the inner practice of protector Kālarūpa, Rinpoché kindly gave me the initiations again, as well as teachings on the visualization procedures and so on.
“The Magical Play of Illusion” by Trijang Rinpoche:
While residing in Dromo, His Holiness observed an approaching retreat on the root mantra of single-deity Vajrabhairava, an
approaching retreat of the Great Compassionate One according to the Lakṣmī tradition, and a retreat on the inner sādhana of Dharmarāja, for
which I served as his assistant.
Ling Rinpoche has received this empowerment from Phabongkha Rinpoché at Yerpa Monastery in the fire-rabbit year of 1927.
“The Jewel-garland Biography of the 97th Gaden Throne Holder Kyabje Yongzin Ling Rinpoche”:
After the teachings on the stages of the path, and with teachings on Aśvaghoṣa’s Fifty Verses on the Guru as a preliminary, Rinpoché received initiations into the thirty-two-deity Akṣobhyavajra mandala of the Ārya tradition of Guhyasamāja, the five-deity outer mandala of the Cakrasaṃvara Ghaṇṭapāda tradition, the thirteen-deity Vajrabhairava mandala, the thirty-seven-deity Vairocana mandala, the nine-deity Akṣobhya mandala, the great initiation of Eleven-Faced Avalokiteśvara of the Bhikṣuṇī Lakṣmī tradition, the permission initiation of the Guhyasamāja, Vajrabhairava, and Cakrasaṃvara mantra formulation, and the initiation of the sixteen drops of the Kadampa.
His Holiness second main guru, Trijang Rinpoche, has also received this empowerment but he doesn`t mention Phabongkha Rinpoche, instead he mentions Buldü Rinpoché.
“The Magical Play of Illusion” by Trijang Rinpoche:
In my fourteenth year, after the Great Prayer Festival in the year of the wood-tiger (1914), Buldü Vajradhara Jetsun Losang Yeshé Tenpai Gyaltsen of Drepung’s Gomang College gave many initiations and teachings in the assembly hall of Kundeling Monastery in Lhasa at the request of Tatsak Hothokthu Rinpoché. Buldü Rinpoché was truly Vajradhara — an allembracing lord of a hundred buddha families who establishes in the minds
of the ocean of living beings whatever paths and fruits of the four bodies of enlightenment in union suit them. He gave full initiations into single-deity
Vajrabhairava, thirteen-deity Vajrabhairava, the Ārya tradition of Akṣobhyavajra Guhyasamāja, the Luipa tradition of sixty-two-deity
Cakrasaṃvara, the Ghaṇṭapāda tradition of five-deity Cakrasaṃvara, and the Great Compassionate One according to the Bhikṣuṇī Lakṣmī tradition, together with preparation, in a painted mandala for each. Other teachings included a discourse on three key points for the yoga of Avalokiteśvara in the Mitrayogin tradition and a discourse on the Nyen Tsembu tradition of Avalokiteśvara yoga.
Meditation retreat by Trijang Rinpoche. “The Magical Play of Illusion” by Trijang Rinpoche:
After completion of the year’s session at the tantric college, I stayed permanently at Chusang, where I spent most of my time attending all the
teachings of Kyabjé Phabongkha Vajradhara. During recesses between discourses, I performed the meditation retreats of the special deities
Vajrayoginī, single-deity and thirteen-deity Vajrabhairava, five-deity Cakrasaṃvara of the Ghaṇṭāpāda tradition, Secret Hayagrīva, and the Great
Compassionate One of the Lakṣmī tradition.
So it is possible that he also received it from Phabongkha Rinpoche during this teachings.
Although Trijang Rinpoche was giving this empowerment often, he didn’t mention giving it to His Holiness The 14th Dalai Lama.
So we have this lineage:
Kälsang Gyatso, the seventh Dalai Lama - ? - Phabongkha Rinpoché - Kyabje Yongzin Ling Rinpoche - His Holiness The 14th Dalai Lama.
