In Buddhism, parinirvana (Sanskrit: परिनिर्वाण parinirvāṇa; Pali: परिनिब्बान parinibbāna; Chinese: 般涅槃, bō niè pán) is the final nirvana, which occurs upon the death of the body of someone who has attained complete awakening (bodhi). It implies a release from the bhavachakra, Saṃsāra, karma and rebirth as well as the dissolution of the skandhas.

The parinibbana of the Buddha is described in the Mahāparinibbāna sutta. Because of its attention to detail, the Mahaparinibbana Sutta (of the Theravada tradition), though first committed to writing hundreds of years after his death, has been resorted to as the principal source of reference in most standard studies of the Buddha's life.

In some Mahayana scriptures (notably the Mahayana Mahaparinirvana Sutra), Parinirvana is explicated as the realm of the eternal true Self of the Buddha.

Accounts of the purported events surrounding the Buddha's own parinirvāṇa are found in a wide range of Buddhist canonical literature. In addition to the Pāli Mahāparinibbāna sutta (DN 16) and its Sanskrit parallels, the topic is treated in the Saṃyutta-nikāya (SN 6.15) and the several Sanskrit parallels (T99 p253c-254c), the Sanskrit-based Ekottara-āgama (T125 p750c), and other early sutras preserved in Chinese, as well as in most of the Vinayas preserved in Chinese of the early Buddhist schools such as the Sarvāstivādins and the Mahāsāṅghikas. The historical event of the Buddha's parinirvāṇa is also described in a number of later works, such as the Sanskrit Buddha-carita and the Avadāna-śataka, and the Pāli Mahāvaṃsa.

Tenga Rinpoche (1932–2012) was a Tibetan teacher (lama) in the Karma Kagyu tradition.

Born in Kham in 1932, Tenga Rinpoche was recognized as a reincarnation of Lama Samten at the age of seven.

As he grew older, he studied at Benchen Monastery and was eventually given the name Karma Tenzin Thinle Namgyal from Situ Rinpoche. Soon after, he was given ordination by Situ Rinpoche and entered a three-year retreat.

He was an expert in mandala painting and sculpture.

In 1959, Tenga Rinpoche left Benchen for Lhasa. After the 14th Dalai Lama left Tibet in relation with the 1959 Tibetan uprising, he escaped with Dilgo Khyentse Rinpoche, and the brother of Dilgo Khyentse, the 9th Sangye Nyenpa Rinpoche. He then eventually traveled to northern India. In India, he settled at Rumtek Monastery, the main seat of the 16th Karmapa. Tenga Rinpoche served the 16th Karmapa for seventeen years, nine of those years in the position of Dorje Lopön.

In 1976 Tenga Rinpoche, he settled in Swayambhunath, Nepal, where he founded a second Benchen Monastery and a retreat center in Pharping.

Kyabjé Drubwang Pema Norbu Rinpoche Tibetan: པདྨ་ནོར་བུ་, Wylie: pad ma nor bu (1932 - March 27, 2009) was the 11th throne holder of the Palyul Lineage of the Nyingma school of Tibetan Buddhism, and said to be an incarnation of Vimalamitra. He was widely renowned in the Tibetan Buddhist world as a master of Dzogchen. He was one of a very few teachers left from his generation who received all his training (in the traditional sense) in Tibet under the guidance of what Tibetan Buddhists consider to be fully enlightened teachers.

The Third Drubwang Pema Norbu Rinpoche, Thubten Lekshed Chokyi Drayang, also known as Do-ngag Shedrub Tenzin Chog-lei Namgyal was born in 1932 the year of the Water Monkey, in the twelfth month, in the Powo region of Kham, East Tibet. He was recognized in 1936 by the Fifth Dzogchen Rinpoche (Thubten Chokyi Dorje) and Khenpo Ngaga Rinpoche (also known as Khenchen Ngagi Wangchuk, Ngawang Palzangpo, or Khenpo Ngagchung). Pema Norbu was formally enthroned by his root teacher, Thubten Chökyi Dawa (1894–1959) the second Choktrul Rinpoche, and Karma Thekchok Nyingpo (1908–1958) the Fourth Karma Kuchen Rinpoche. He trained at the Palyul Monastery in Tibet, studying and receiving teachings from numerous masters and scholars, including the Fourth Karma Kuchen, the 10th Palyul throneholder.

Gautama Buddha or Siddhārtha Gautama Buddha (Sanskrit: सिद्धार्थ गौतम बुद्ध; Pali: Siddhattha Gotama) was a spiritual teacher from the Indian subcontinent, on whose teachings Buddhism was founded. The word Buddha is a title for the first awakened being in an era. In most Buddhist traditions, Siddhartha Gautama is regarded as the Supreme Buddha (P. sammāsambuddha, S. samyaksaṃbuddha) of our age, "Buddha" meaning "awakened one" or "the enlightened one." Gautama Buddha may also be referred to as Śākyamuni (Sanskrit: शाक्यमुनि "Sage of the Śākyas"). The Buddha found a Middle Way that ameliorated the extreme asceticism found in the Sramana religions.

The time of Gautama's birth and death are uncertain: most early 20th-century historians dated his lifetime as c. 563 BCE to 483 BCE, but more recent opinion dates his death to between 486 and 483 BCE or, according to some, between 411 and 400 BCE. UNESCO lists Lumbini, Nepal, as a world heritage site and birthplace of Gautama Buddha. There are also claims about birth place of Gautama Buddha to be Kapileswara, Orissa or Kapilavastu at Piprahwa, Uttar Pradesh He later taught throughout regions of eastern India such as Magadha and Kośala.

Trulshik Rinpoche Ngawang Chökyi Lodrö ('khrul zhig ngag dbang chos kyi blo gros) (1 January 1923 – 2 September 2011) born in Yardrok Taklung, Central Tibet was one of the main teachers of HH the 14th Dalai Lama and of many of the younger generation of Nyingma lamas today including Sogyal Rinpoche. He is considered the spiritual heir of several senior Nyingma masters of the last century such as Dudjom Rinpoche and Dilgo Khyentse Rinpoche. Rinpoche is the subject of a documentary film Destroyer of Illusion narrated by Richard Gere. Trulshik Rinpoche founded the monastery of Thubten Chöling in Nepal. In 2010 he became the official head of the Nyingma school.

Rinpoche lived in Solukhumbu, Nepal.

His Holiness Trulshik Rinpoche died on September 2, 2011 (Friday). He has been followed by Taklung Tsetrul Rinpoche who accepted the position on 22 March, 2012.
