The Benchen Monastery official page posted the details of Tenga Rinpoche’s last days and hours.
Here what is mentioned about his next incarnation:
Tashi Ozer asked Rinpoche how and when one should begin to look for Rinpoche’s next incarnation. Tenga Rinpoche was very explicit about it saying “Ask H.H. the Karmapa! His advice will be very clear.”
Tenpa Yarpel then requested Kyabje Tenpa Rinpoche to please return very quickly, to which Rinpoche smiled and nodded his head.
Also of notice, H.E. Sangye Nyenpa Rinpoche already composed a prayer for Tenga Rinpoche swift rebirth.
