Kunzang Gongdu is the complete cycle of Dzogchen, means "the totality of Samantabhadra's Enlightened Intentions" and emphasis Khandro Nyingtig. From http://yeshekhorlo.org/pemaLingpaLineage
"Princess Pemasel revealed the Khandro Nyingtig teachings and taught on them extensively in her next incarnation as Pema Lendreltsel, who later took rebirth as the great master Longchen Rabjampa (Longchenpa). Pema Lingpa was the direct and sole incarnation of the omniscient Longchenpa.
The revealed treasures of Pema Lingpa contain the essence of all 108 treasures, which are summarized in the cycles of the three heart practices transmitted to Princess Pemasel by Guru Rinpoche (Lama Jewel Ocean, Samantabhadra's Intentions, and the Great Compassionate One)."
