At the age of five, having been identified as the reincarnation of the Second Purchok, Lobzang Jampa (pur bu lcog 02 blo bzang byams pa, 1763-1825), Jampa Gyatso was escorted to U and installed in the Purchok Hermitage (pur bu lcog ri khrod) above Sera Monastery (se ra dgon)outside of Lhasa. He began his basic education in reading and writing, and memorization of daily prayer-texts under a man named Ne Lama (gnas bla ma), the master of the hermitage at that time.
At the age of ten, Jampa Gyatso matriculated in the Sera Je College (se ra bye) for his further studies. The Tenth Dalai Lama, Tsultrim Gyatso (ta la'i bla ma 10 tshul khrims rgya mtsho, 1816-1837) cut his crown-hair and gave him the name Jampa Tsultrim Gyatso (byams pa tshul khrims rgya mtsho) in 1734. Subsequently the Seventh Paṇchen Lama Lobzang Tenpai Nyima Chole Namgyel (paN chen bla ma 07 blo bzang bstan pa'i nyi ma phyogs las rnam rgyal, 1781-1854) granted him the vows of novice monk.
Jampa Gyatso studied Abhisamayālaṃkāra, Madhyamaka, Abhidharmakośa, Pramāṇavārttika and Vinaya, the major subjects of the Geluk monastic curriculum, under a number of masters, including Geshe Drakpa Tsondu (dge bshes grags pa brtson 'grus, d.u.) who served as his principal tutor. He took the first traditional exam on Prajñāpāramitā in 1839, followed by three more exams. In the meantime, at the age of twenty, he received the vows of full ordination from the Seventh Paṇchen Lama. He became a competent scholar, and earned his Geshe Lharampa degree at the examinations during the Lhasa Monlam when he was twenty-one.
At the age of thirty-seven, Purchok Jampa Gyatso served as the tutor to the Twelfth Dalai Lama, Trinle Gyatso (ta la'i bla ma 12 'phrin las rgya mtsho, 1857-1875). Nearly two decades later, at the age of fifty-three, he served as the tutor to the Thirteenth Dalai Lama Tubten Gyatso (tA la'i bla ma 13 thub bstan rgya mtsho, 1876-1933). Purchok gave teachings, empowerments and initiations, transmissions and instructions on various important topics of both sutra and tantra to the two Dalai Lamas. He also gave the vows of full ordination to the Thirteenth Dalai Lama.
Purchok Jampa Gyatso passed into nirvana in 1901, the iron-ox year of the fifteenth sexagenary cycle, at the age of seventy-seven. The Thirteenth Dalai Lama supervised the funeral. One source has it that he lived at the age of seventy and passed in 1894, the wood-horse year in the fifteenth sexagenary cycle, but this is in error.
