Adi-Buddha in the context of "List of Buddhas"

In Buddhism, Buddha (/ˈbuːdə, ˈbʊdə/, which in classic Indic languages means "awakened one") is a title for those who are spiritually awake or enlightened, and have thus attained the supreme goal of Buddhism, variously described as awakening or enlightenment (bodhi), Nirvāṇa ("blowing out"), and liberation (vimokṣa). A Buddha is also someone who fully understands the Dhārma, the true nature of all things or phenomena (dhārmata), the ultimate truth. Buddhahood (Sanskrit: buddhatva; Pali: buddhatta or buddhabhāva; Chinese: 成佛) is the condition and state of being a Buddha. This highest spiritual state of being is also termed sammā-sambodhi (Sanskrit: samyaksaṃbodhi; "full, complete awakening" or “complete, perfect enlightenment”) and is interpreted in many different ways across schools of Buddhism.

The title of "Buddha" is most commonly used for Gautama Buddha, the historical founder of Buddhism, who is often simply known as "the Buddha". The title is also used for other sentient beings who have achieved awakening or enlightenment (bodhi) and liberation (vimokṣa), such as the other human Buddhas who achieved enlightenment before Gautama; members of the Five Buddha Families such as Amitābha; and the bodhisattva Maitreya, known as the "Buddha of the future who will attain awakening at a future time."

Vajradhara (Sanskrit: वज्रधर, lit. 'Diamond-holder'; Tibetan: རྡོ་རྗེ་འཆང, Wylie: rdo rje 'chang, THL: Dorje Chang; Chinese: 金剛總持; pinyin: Jīngāng Zǒngchí; Javanese: Kabajradharan; Japanese: 持金剛仏; Mongolian: Очирдар, romanized: Ochirdar; Vietnamese: Kim Cang Tổng Trì) is the ultimate primordial Buddha, or Adi-Buddha, according to the Sakya, Gelug and Kagyu schools of Tibetan Buddhism. It is also a name of Indra, because "Vajra" means diamond, as well as the thunderbolt, or anything hard more generally.

In the evolution of Indian Buddhism, Buddha Vajradhara gradually displaced Samantabhadra, who is the 'Primordial Buddha' in the Nyingma, or 'Ancient School.' However, the two are metaphysically equivalent. Achieving the 'state of Vajradhara' is synonymous with complete realisation.

The Kāraṇḍavyūha Sūtra ("The Basket's Display", Full Sanskrit: Āryakāraṇḍavyūhanāmamahāyānasūtra, Tibetan: ['phags pa] za ma tog bkod pa zhes bya ba theg pa chen po'i mdo; Chinese: 佛說大乘莊嚴寶王經; pinyin: Fó shuō dàchéng zhuāngyán bǎo wáng jīng; Jyutping: fat6 syut3 daai6 sing4 zong1 jim4 bou2 wong4 ging1) is a Mantrayāna sūtra which extols the virtues and powers of Avalokiteśvara, who is presented here as a primordial cosmic overlord (a kind of adibuddha figure) and as the source of numerous Indian deities.

The Kāraṇḍavyūha was compiled at the end of the 4th century or beginning of the 5th century CE. It exists in Chinese translation (at Taishō Tripiṭaka no. 1050) and in Tibetan (Tohoku no. 116). This sutra is particularly notable for introducing the mantra Om mani padme hum and also teaching the important Cundi dharani.

Nichiren (日蓮; Japanese pronunciation: [ɲi.tɕiꜜ.ɾeɴ, ɲiꜜ.tɕi.ɾeɴ], 6 April 1222 – 13 October 1282) was a Japanese Buddhist monk and philosopher of the Kamakura period. His teachings form the basis of Nichiren Buddhism, a unique branch of Japanese Mahayana Buddhism based on the Lotus Sutra.

Nichiren declared that the Lotus Sutra alone contains the highest truth of Buddhism and that it is the only sutra suited for the Age of Dharma Decline. He insisted that the sovereign of Japan and its people should support only this form of Buddhism and eradicate all others, or they would face social collapse and environmental disasters. Nichiren advocated the faithful recitation of the title of the Lotus Sutra, Namu Myōhō Renge Kyō, as the only effective path to Buddhahood in this very life, a path which he saw as accessible to all people regardless of class, education or ability. Nichiren held that Shakyamuni and all other Buddhist deities were manifestations of the Original Eternal Buddha (本仏 Honbutsu) of the Lotus Sutra, which he equated with the Lotus Sutra itself and its title. He also declared that believers of the Lotus Sutra must propagate it even though this would lead to many difficulties and even persecution, which Nichiren understood as a way of "reading" the Lotus Sutra with one's very body. Nichiren believed that the spread of the Lotus Sutra teachings would lead to the creation of a Pure Land on earth.

Nyingma (Tibetan: རྙིང་མ་, Wylie: rnying ma, Lhasa dialect: [ɲ̟iŋ˥˥.ma˥˥], lit. 'old school'), also referred to as Ngagyur (Tibetan: སྔ་འགྱུར་རྙིང་མ།, Wylie: snga 'gyur rnying ma, Lhasa dialect: [ŋa˥˥.ʈ͡ʂuɹ], lit. 'order of the ancient translations'), is the oldest of the four major schools of Tibetan Buddhism. The Nyingma school was founded by Padmasambhava as the first translations of Buddhist scriptures from Pali and Sanskrit into Tibetan occurred in the eighth century. The establishment of Tibetan Buddhism and the Nyingma tradition is collectively ascribed to Khenpo Shantarakshita, Guru Padmasambhava, and King Trisong Detsen, known as Khen Lop Chos Sum (The Three: Khenpo, Lopon, Chosgyal).

The Nyingma tradition traces its Dzogchen lineage from the first Buddha Samantabhadra to Garab Dorje, and its other lineages from Indian mahasiddhas such as Sri Singha and Jnanasutra. Yeshe Tsogyal recorded the teachings. Other great masters from the founding period include Vimalamitra, Vairotsana, and Buddhaguhya. The Nyingma tradition was physically founded at Samye, the first monastery in Tibet. Nyingma teachings are also known for having been passed down through networks of lay practitioners, and of Ngakmapas (Skt. mantrī).

Samantabhadra (lit. 'Universal Worthy' or 'All Good') is a great bodhisattva in Buddhism associated with practice and meditation. Together with Shakyamuni Buddha and the bodhisattva Mañjuśrī, he forms the Shakyamuni Triad in Mahayana Buddhism. He is the patron of the Lotus Sutra and, according to the Avatamsaka Sutra, made the ten great vows which are the basis of a bodhisattva.

In Chinese Buddhism, Samantabhadra is known as Puxian and is associated with action, whereas Mañjuśrī is associated with prajñā (transcendent wisdom). As such, his name is often prefixed with the epiphet Daheng (大行; Dàhèng), meaning “He of Great Practice”. In the Huayan tradition, he is regarded together with Vairocana Buddha and the bodhisattva Mañjuśrī as one of the “Three Noble Ones of Huayan” (華嚴三聖; Huāyán Sānshèng) due to their preeminence in the Avatamsaka Sutra. In the Chinese Pure Land tradition, the Chapter of the Practices and Vows of Bodhisattva Samantabhadra from the Avatamsaka Sutra where Samantabhadra expounds on his ten vows is often regarded as one of the “Five Pure Land sutras” that are seen as foundational texts. In Japan, Samantabhadra is known as Fugen, and is often venerated in Tendai and Shingon Buddhism. In the Nyingma school of Tibetan Buddhism, Samantabhadra is also the name of the Adi-Buddha, often portrayed in indivisible union (yab-yum) with his consort, Samantabhadrī. In wrathful form he is one of the Eight Herukas of the Nyingma Mahayoga and he is known as Vajramrtra, but this Samantabhadra buddha and Samantabhadra bodhisattva are not the same.
