The third of the five paths; the stage of spiritual attainment in which one witnesses the true nature of reality for the first time, progressing to the level of a noble one. [TD 1222] +
Along with the completion stage, this is one of two phases that constitute Buddhist practice in the inner tantras. Explaining this approach, Ju Mipham writes, "The phases of development stage practice correspond to the way in which conventional existence develops. There are five such phases: great emptiness, illusory wisdom, the single seal, the elaborate seal, and group assembly practice. Practicing this fivefold approach ''purifies'' the habitual patterns of saṃsāra, ''perfects'' the fruition of nirvāṇa, and ''matures'' the practitioner for the completion stage. [ON 416] +
The so-called "union of development and completion" seems to have been a controversial theory in Tibet. Confirming this view, Khenpo Ngaga writes, "There are those who do not accept the union of development and completion associated with deity meditation. They justify this view by saying that such an approach did not exist in the noble land of India. This, however, is not the case. There are two renowned approaches linked with the ''Guhyasamāja Tantra'', one associated with noble Nāgārjuna and another with Jñānapāda. In the latter approach, it is said that, when meditating on a deity, those who have directly experienced the way things truly are 'seal the development stage with the completion stage.'" [ST 8-9] +
One of the five kāyas; encompassing all the manifestations of knowledge, love, and ability, this kāya is the basis for all the unique qualities of buddhahood. [NS 140] +
The secret empowerment is the first of the three higher supreme empowerments (the other two being the knowledge-wisdom empowerment and the precious word empowerment). This is bestowed upon the ordinary speech of the student by relying upon the maṇḍala of the relative enlightened mind of the male and female teachers in union. This purifies the impurities of ordinary speech. In terms of the path, this empowers one to meditate on the energetic practices and recite mantra. In terms of the fruition, a link is formed to the attainment of the sambhogakāya and vajra speech. [TD 3006] +
The samaya being is one of the three beings set forth in development stage practice. This is the deity that one visualizes in conjunction with the ritual of which ever yidam deity is being practiced. [TK 3, 45] According to Jamgön Kongtrül, the samaya being corresponds to the luminous, enlightened mind. This, in turn, is inseparable from the wisdom being, the dharmakāya of all buddhas. [LW 62] +
Quoting the ''Sūtra of the Levels of Buddhahood'', Jigme Lingpa explains, "The wisdom of the basic space of phenomena can be exemplified by all the forms space can take. Although space is present in these forms, by its very nature there is nothing that can be said about it; it is not manifold, but of a single taste. In the same way, though the wisdom of the basic space of phenomena is present in everything that can be known, it is ineffable. And since it isn't manifold, it is of one taste." [YT 431] +
1) That which is unchanging and indestructible; 2) an ancient Indian symbol that, of skillful means and knowledge, is used to symbolize knowledge; 3) one of the twenty-seven coincidences in Tibetan astrology; 4) an abbreviation of the Tibetan word for diamond. [TD 1438] In Vajrayāna practice, this symbolic implement is associated with a number of important principles. Generally speaking, it is linked with the male principle, compassion, skillful means, and the great bliss of unchanging reality. [YT 671] +
Mahāyoga is traditionally divided into two groups, the Collected Tantras, which includes the ''Guhyagarbha Tantra'', and the Collected Sādhanas. The latter division contains the Eight Great Sādhana Teachings, which comprise the ritual practices and instructions associated with eight divinities - five transcendent deities and three mundane deities. The five wisdom deities are Mañjuśrī Yamāntaka (enlightened form), Padma Hayagrīva (enlightened speech), Viśuddha (enlightened mind), Vajramṛta Mahottara (enlightened qualities), and Vajrakīlaya (enlightened activity). The three classes of worldly divinities are Mātaraḥ (liberating sorcery), Lokastotrapūja (mundane praises), and Vajramantrabhīru (wrathful mantra). [NS 283] These teachings have been maintained and practiced in both the Transmitted Teachings and the treasure tradition. In the former, the primary source is a cycle titled the ''Fortress and Precipice of the Eight Teachings: The Distilled Realization of the Four Wise Men''. There are a great many related teachings in the treasure tradition, the most important, however, are found in the revelations of Nyang Ral Nyima Özer, Guru Chöwang, and Rigdzin Gödem. [WC 777] +
oṃ svabhāva śuddhaḥ sarvadharmāḥ svabhāva haṃ; This mantra is commonly used at the outset of development stage practice to dissolve all phenomena into emptiness (prior to developing the visualization). Tsele Natsok Rangdröl explains, "One begins the development stage with purifying into emptiness by means of the svabhāva mantra. This mantra is meant to remind the practitioner of the essence of emptiness, the original natural state of all phenomena ... It is precisely the natural expression of this emptiness, the magical display of its unceasing cognizant quality, that emanates and manifests in the form of a celestial palace and various types of deities." [EM 88] +
To specific disciples it is taught that the profound nature of all phenomena is emptiness, free from arising, cessation, and every other form of conceptual projection, and that the actual condition and nature of things is one of luminosity, beyond anything that can be thought or put into words. The definitive meaning is this nature, as well as the scriptures that teach it and their related commentaries. [TD 655] +
Vajra recitation is the practice of linking mantra recitation with movements of the breath. This often involves linking the inhalation, resting, and exhalation of the breath with the mental recitation of the seed syllables OṂ AḤ HūṂ, while simultaneously holding the vase breath. [NO 4, 20] +
[Lit. "heroic being of enlightenment"] - An individual who trains in the Great Vehicle, so-called because such individuals do not become discouraged in the face of the long duration it takes to attain great enlightenment, nor in giving away their own head and limbs out of generosity. [TD 1870] +
