I figured I mention this in a separate thread about him being in Tukdam.
Dear Friends,
This Jetsun Yogi Lotsawa Heruka Losang Tsering (David Gonsalez) Rinpoche, it should be known was previously the son of the human woman who became the Dharma Protector Jetsunma Palden Lhamo; that he was a quiet Tulku in this present life - definite close student of Trijang Dorjechang in his immediate previous life, and close disciple of other Heruka lineage Gurus such as Sonam Tsemo. Though stories of miraculous occurrences and such could be shared, it is principally his extensive work for living beings that shines very brightly, particularly his life work completing many profound translations of Tibetan texts available at Dechen Ling Press website, where several tributes to him can now be read.
You as a practitioner should know this in particular: he completed the 9 preliminaries, over 40 fully qualified retreats with subsequent fire pujas, 100's of auxiliary fire pujas, his daily practice lasted appx 6hrs and included without missing a single day for many many years such things as Lama Chopa, Heruka body mandala self-initiation, Palden Lhamo Kangso and many other things, with very special emphasis on bodhichitta. He was incredibly steadfast with his vows and commitments, was constantly studying many Dharma texts, and at the close of this training remained in his final meditation of Tukdam for 3 days after the heart and breathing ceased. His example should be a lesson to the lazy, the doubtful, and those who are diligent needing further inspiration, that with true devotion and diligence in genuine practice great things can be accomplished!
I bow most respectfully to this Lord of Yoga. The world will be worse off without your emanation, Great Yogi Lotsawa Losang Tsering Rinpoche!
