Dzogchen in the context of "Mahasiddha"

Svabhava (Sanskrit: स्वभाव, svabhāva; Pali: सभाव, sabhāva; Chinese: 自性; pinyin: zìxìng; Vietnamese: Tự tính; Tibetan: རང་བཞིན, Wylie: rang-bzhin) literally means "own-being" or "own-becoming". It is the intrinsic nature, essential nature or essence of beings.

The concept and term svabhāva are frequently encountered in Hindu and Buddhist traditions such as Advaita Vedanta (e.g. in the Avadhūta Gītā), Mahāyāna Buddhism (e.g. in the Ratnagotravibhāga), Vaishnavism (e.g., the writings of Ramanuja) and Dzogchen (e.g. in the seventeen tantras).

Luminous mind (Skt: prabhāsvara-citta or ābhāsvara-citta, Pali: pabhassara citta; Tib: འོད་གསལ་གྱི་སེམས་ ’od gsal gyi sems; Ch: 光明心 guangmingxin; Jpn: 光明心 kōmyōshin) is a Buddhist term that appears only rarely in the Pali Canon, but is common in the Mahayana sūtras and central to the Buddhist tantras. It is variously translated as "brightly shining mind" or "mind of clear light", while the related term luminosity (Skt. prabhāsvaratā; Tib. འོད་གསལ་བ་ ’od gsal ba; Ch. guāng míng; Jpn. kōmyō; Kor. kwangmyōng) is also translated as "clear light" or "luminosity" in Tibetan Buddhist contexts or "purity" in East Asian contexts.

The Theravada school identifies the "luminous mind" with the bhavanga, a concept first proposed in the Theravāda Abhidhamma. The later schools of the Mahayana identify it with bodhicitta and tathagatagarbha. The luminosity of mind is of central importance in the philosophy and practice of the Buddhist tantras, Mahamudra, and Dzogchen.

A charnel ground (Sanskrit: श्मशान; IAST: śmaśāna; Tibetan pronunciation: durtrö; Tibetan: དུར་ཁྲོད, Wylie: dur khrod) is an above-ground site for the putrefaction of bodies, generally human, where formerly living tissue is left to decompose uncovered. Although it may have demarcated locations within it functionally identified as burial grounds, cemeteries and crematoria, it is distinct from these as well as from crypts or burial vaults.

In a religious sense, it is also a very important location for sadhana and ritual activity for Indo-Tibetan traditions of Dharma, particularly those traditions iterated by the Tantric view such as Kashmiri Shaivism, Kaula tradition, Esoteric Buddhism, Vajrayana, Mantrayana, Dzogchen, and the sadhana of Chöd, Phowa and Zhitro, etc. The charnel ground is also an archetypal liminality that figures prominently in the literature and liturgy and as an artistic motif in Dharmic Traditions and cultures iterated by the more antinomian and esoteric aspects of traditional Indian culture.

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).

Udiana (also: Uḍḍiyāna, Uḍḍāyāna, Udyāna or 'Oḍḍiyāna'), a small region in early medieval India, is ascribed importance in the development and dissemination of Vajrayāna Buddhism. Tibetan Buddhist traditions view it as a Beyul (Tibetan: སྦས་ཡུལ, Wylie: sbas-yul), a legendary heavenly place inaccessible to ordinary mortals. Padmasambhava, the eighth-century Buddhist master who was instrumental in the introduction of Buddhism to Tibet, was believed to have been born in Oddiyana. The Dzogchen Siddha Garab Dorje is likewise attributed to this region.

It is ascribed importance in the development and dissemination of Vajrayāna Buddhism. The region was also an important place for the practice of Śaivite Hinduism. It is seen as the homeland of the Mahārtha (aka Krama Kalikula) lineage of Śaiva Tantra. The first Mahārtha Siddha, Jñānanetra Nātha, is said to have awakened and taught in this country. It was also called as “the paradise of the Ḍākinīs”.

The Seventeen Tantras of the Esoteric Instruction Series (Tibetan: མན་ངག་སྡེའི་རྒྱུད་བཅུ་བདུན, Wylie: man ngag sde'i rgyud bcu bdun) or the Seventeen Tantras of the Ancients (rnying-ma'i rgyud bcu-bdun) are an important collection of tantras in the Nyingma school of Tibetan Buddhism. They comprise the core scriptures of the "esoteric instruction series" (Menngagde) of Dzogchen teachings and are its most authoritative scriptures.

The Seventeen Tantras are part of the Vima Nyingthig ("Inner Essence of Vimalamitra"), a terma cycle of Dzogchen texts revealed by the treasure discoverer Zhangton Tashi Dorje (c. 1097-1127) and associated with the 8th century Indian monk Vimalamitra who is traditionally believed by the Nyingma school to have first brought these texts to Tibet.

In Tibetan Buddhism, Ngöndro (Tibetan: སྔོན་འགྲོ།, Wylie: sngon 'gro, Sanskrit: pūrvaka) refers to the preliminary, preparatory or foundational practices or disciplines (Sanskrit: sādhanā) common to all four schools of Tibetan Buddhism and also to Bon. They precede deity yoga.

The preliminary practices establish the foundation for the more advanced and esoteric Vajrayana sādhanā which are held to engender realization and the embodiment of Dzogchen, Heruka and Mahamudra.

Sūtrayāna (Sanskrit: सूत्रयान) is the Indo-Tibetan three-fold classification of yanas. A yana is a Buddhist mode of practice that leads to the realization of emptiness. The three yanas of the Sutrayana are Sravakayana or Pratyekabuddhayana, Mahayana, and Vajrayana. The third yana, Vajrayana, comprises Tantrayana and Dzogchen.

Most often, Sūtrayāna is a classification used in the Vajrayāna to refer to the vehicles of Śrāvakayānana and Mahāyāna, based on the sutras, as a whole. In this context, Sūtrayāna is also known as the causal vehicle, as the six Paramita, thirty-seven factors of enlightenment, ethical and intellectual disciplines and a variety of methods are practiced as causes for achieving the final result. Buddhahood emerges as the result when all such causes are complete. Vajrayāna, vehicle based on Mahāyāna, and on the sutras as well as on the tantras, is also known as the resultant vehicle because the path is not based only on establishing the cause, but identifying directly with the fruition — the fundamentally pure essence of mind, or Buddha-nature.
