After reporting all this to the king, the king sent the Chagzoe to Kalimpong in order to interview Dudjom Rinpoche. The Chagzoe told the high lama, who was Tulshuk Lingpa’s root guru, ‘I’ve’ just come from Tashiding where I interviewed Tulshuk Lingpa and he told me everything. Some say he’s not serious about actually going to Beyul but he brought his khandro, a sure indication that he has every intention of opening the gate. He told me everything but he wouldn't tell me when he would depart. He is your disciple so you must know when. So please tell me.’
Dudjom Rinpoche said, diplomatically but to the point, ‘Tulshuk Lingpa is a terton, and Beyul does exist. He is the right man to open Beyul. I have no idea about the timing. Only he can know this.’
