Gyaltsap rinpoches have helped identify five incarnations (both include recognition of Ogyen Trinley Dorje). Chokgyur Lingpa's prophecy of 17th Karmapa and Tai Situ Rinpoche A prophecy was made by the 19th century Nyingma master, Chokgyur Lingpa, based a vision he had whereby Guru Rinpoche manifests as past and future Karmapas, and the minds of the 17th Karmapa and Tai Situ Rinpoche are "inseparably one" as they sit together under a "verdant tree on a rocky mountain". While disputing the interpretation of the prophecy, the Shamarpa, while supporting his selection of Trinley Thaye Dorje, maintained it could be reinterpreted to correspond to the 16th Karmapa and the 11th Tai Situ Rinpoche. The 14th Dalai Lama In Tibet, the 14th Dalai Lama's Gelug school historically had a strong political and spiritual-leadership role, which was tempered by the autonomy of the three other schools of Tibetan Buddhism—the Kagyu school, the Nyingma school and the Sakya school. The Nyingma school has always been non-political. The 13th Dalai Lama sought to modernize the political state, and the young 14th Dalai Lama interacted with the Communist political system after 1949, then attempted peace talks, while accompanied by the Panchen Lama and others, in 1955. After China's invasion turned brutal in 1959 and his incarnation was threatened, he went into exile and repudiated all agreements with China. In 1963, the Tibetan Government-in-Exile introduced democratic reforms, and in 2011, the Dalai Lama resigned from his political position to continue as a spiritual leader. During this period in 1992, after Ogyen Trinley Dorje was located and recognized, the search committee, then led by Tai Situ Rinpoche, requested that the Dalai Lama bestow the Buktham Rinpoche seal, or the Buktham Letter, on the recognized 17th Gyalwang Karmapa. The seal was made official on 30 June 1992. Supporters of Ogyen Trinley Dorje maintain that the 14th Dalai Lama has the spiritual authority to recognize an incarnation of the Karmapa. The Karmapa lineage is the oldest tulku lineage in Tibetan Buddhism, predating the Dalai Lama lineage by more than two centuries. Followers of the Karma Kagyu lineage historically have considered themselves independent of the Dalai Lama's authority, and see the Karmapas as spiritually equal to the historical Buddha. Supporters of Trinley Thaye Dorje claim any previous involvement of the Dalai Lama and Tibetan government was merely a final stamp of approval following an individual monastery's (or lama's administration) independent decision.
