The Vajra
Indra's Weapon, Made Indestructible
- First attested
- around 1200 BCEIndra's vajra is Ṛgvedic: at 1.32.2, in Griffith's 1896–97 English, "He slew the Dragon lying on the mountain: his heavenly bolt of thunder Tvashṭar fashioned." Jamison and Brereton place the hymns in the later second millennium BCE. The oldest vajra this entry can point to as a surviving object is the Metropolitan Museum's Gandhāran relief 1980.527.4, "Vajrapani Attends the Buddha at His First Sermon", schist, catalogued ca. 2nd century — a bar, not a five-pronged sceptre. For the tantric redefinition, Snellgrove's 1959 glossary states it plainly: in Vedic times the divine weapon of Indra, thereafter symbolising "pre-eminently whatever is believed to be indestructible; thus it also has the meaning of 'diamond'." Steven Weinberger dates the Compendium of Principles to the last quarter of the seventh century in south India, arguing from Vajrabodhi's receiving teachings on it in 700 and a Chinese text of 723 whose passages match its first chapter; Amoghavajra translated that chapter in 753 and, between 746 and 771, wrote the Indications of the Goals of the Eighteen Assemblies, a summary of the eighteen-text cycle of which the Compendium is the first and preeminent member. Five-pronged vajras and vajra-handled bells survive as Tang and Heian metalwork in Japanese collections: the Nara National Museum's eighth-century Tang bell, whose record reads the small holes between its prongs as "suggesting an intriguing connection" with the relic-holding implements described in Kūkai's list of what he brought back from China, and a tenth-century Heian pestle in Cleveland. The Tibetan side arrives later: Weinberger has Yeshé Ö dispatching Rinchen Zangpo (958–1055) and others to Kashmir specifically for the Compendium of Principles and Guhyasamāja systems.
The vajra is Indra's thunderbolt taken over: a weapon the Ṛgveda made for smashing became, in tantras compiled from the late seventh century, the emblem of what cannot be smashed — and the earliest five-pronged examples this entry can point to are not Tibetan but an eighth-century Tang bell and a tenth-century Heian pestle, both in Japan.
A ritual scepter representing the irresistible force of a thunderbolt and the indestructible clarity of a diamond.
Vajra is Indra's weapon. In Ṛgveda 1.32 the storm god smashes the dragon Vṛtra with a bolt Tvaṣṭar forged for him. Buddhism took weapon and name: in Gandhāran schist of the second century a bare-chested Vajrapāṇi — vajra-in-hand — attends the Buddha's first sermon holding a plain bar, not a pronged sceptre. The tantras then turned the word over. Snellgrove glosses vajra as whatever is held indestructible, hence also diamond; the vehicle is named for the object. That layer is datable: Weinberger places the Compendium of Principles in south India in the last quarter of the seventh century, and Amoghavajra summarised its eighteen-text cycle in China between 746 and 771. The five-pronged dorje came later: the earliest such pieces this entry can point to are an eighth-century Tang bell and a tenth-century Heian pestle, both in Japanese collections.
Light
Half of a pair. Karma Phuntsho, for the Rubin Museum, gives the vajra as skilful method or compassion, the bell as wisdom, the five prongs as the buddhas of the five families; the same essay's Padmasambhava wields his dorje right-handed. Neither works alone.
Shadow
Snellgrove's glossary records the tantras' own concealed sense of the word: vajra is the male organ, paired with lotus. The same word titles the teacher, vajrācārya, and names the pupil under consecration, vajradhṛk — an emblem of the unbreakable doubling as a vocabulary of rank.
