Absolutely. It's the Dzinpa Rangdröl, and it is a Terma of Do Khyentse Yeshe Dorje centered around Chöd and Machig Labdrön. Nyala Pema Duddul, a heart student of Do Khyentse, received the lineage directly from him and taught it to Ayu Khandro, who practiced it while wandering through Tibet and transmitted it to Namkhai Norbu Rinpoche, though he has never openly taught it. Norbu Rinpoche is a main teacher of Lama Tsultrim's, and he was rather amazed to hear that the Dzinpa Rangdröl came to Tara Mandala. We received it from Tulku Sang-Ngag Rinpoche, who received it from Dilgo Khyentse Rinpoche. The transmission of the whole lineage was the result of Lama Tsultrim (recognized as an emanation of Machig by Lama Wangdu and Karma Dorje Rinpoche, the resident Lama at Machig's seat in Tibet) asking if there is a lineage that really blends Machig's Chöd with Dzogchen. Tulku Sang-Ngag immediately recollected the Dzinpa Rangdröl.
Adzom Rinpoche, an esteemed mahasiddha and Tertön who has been instrumental in bringing the Longchen Nyingthik and Osel Dorje Sangngag Dzöd to Tara Mandala, has also been receiving commentaries and instructions on Dzinpa Rangdröl as Gongter from Nyala Pema Duddul throughout his life. He's been under house arrest in Tibet for the better part of the last decade, and since the Dzinpa Rangdröl is relatively new at Tara Mandala, he never thought to tell Lama Tsultrim about these Termas. But when he discovered that we are establishing the lineage at TM, he was ecstatic, and described the stack of Terma from NPD that he received on the cycle.
So, all in all, it seems that the karmic connection to the Dzinpa Rangdröl, and mysteriously to Nyala Pema Duddul, is very strong at Tara Mandala, and therefore the blessings are vast.
It should also be noted that the stupa was built a decade before the Dzinpa Rangdröl was even known about at Tara Mandala.
