BhairavaBhairava (भैरव, frightful), or Kala Bhairava, is a Shaivite and Vajrayāna deity worshiped by Hindus and Buddhists. In Shaivism, he is a powerful manifestation, or avatar, of Shiva associated with annihilation. In Trika system Bhairava represents Supreme Reality, synonymous to Para Brahman. Generally in Hinduism, Bhairava is also called Dandapani ("[he who holds the] Danda in [his] hand"), as he holds a rod or Danda to punish sinners, and Svaśva, meaning "whose vehicle is a dog".
Charnel groundA charnel ground (Sanskrit: श्मशान; IAST: śmaśāna; Tibetan pronunciation: durtrö; ) 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.
VajraThe Vajra (वज्र) is a legendary and ritualistic weapon, symbolizing the properties of a diamond (indestructibility) and a thunderbolt (irresistible force). The vajra is a type of club with a ribbed spherical head. The ribs may meet in a ball-shaped top, or they may be separate and end in sharp points with which to stab. The vajra is the weapon of Indra, the Vedic king of the devas and heaven. It is used symbolically by the dharmic traditions of Hinduism, Buddhism, and Jainism, often to represent firmness of spirit and spiritual power.
MahasiddhaMahasiddha (Sanskrit: mahāsiddha "great adept; ) is a term for someone who embodies and cultivates the "siddhi of perfection". A siddha is an individual who, through the practice of sādhanā, attains the realization of siddhis, psychic and spiritual abilities and powers. Mahasiddhas were practitioners of yoga and tantra, or tantrikas. Their historical influence throughout the Indian subcontinent and the Himalayas was vast and they reached mythic proportions as codified in their songs of realization and hagiographies, or namtars, many of which have been preserved in the Tibetan Buddhist canon.
AghoriThe Aghori (from Sanskrit अघोर aghora; not-fearful', 'fearless) are a monastic order of ascetic Shaivite sadhus based in Uttar Pradesh, India. They are the only surviving sect derived from the Kāpālika tradition, a Tantric, non-Puranic form of Shaivism which originated in Medieval India between the 7th and 8th century CE. Similarly to their predecessors, Aghoris usually engage in post-mortem rituals, often dwell in charnel grounds, smear cremation ashes on their bodies, and use bones from human corpses for crafting kapāla (skull cups which Shiva and other Hindu deities are often iconically depicted holding or using) and jewellery.
TantraTantra (ˈtæntrə; तन्त्र) refers to an esoteric yogic tradition that developed on the Indian subcontinent from the middle of the 1st millennium CE onwards in both Hinduism and Buddhism. The term tantra, in the Indian traditions, also means any systematic broadly applicable "text, theory, system, method, instrument, technique or practice". A key feature of these traditions is the use of mantras, and thus they are commonly referred to as Mantramārga ("Path of Mantra") in Hinduism or Mantrayāna ("Mantra Vehicle") and Guhyamantra ("Secret Mantra") in Buddhism.
