The homa is a votive offering involving the construction of a fire in a hearth-altar, and the immolation of offerings in the fire. The altar is homologized with a mandala, and as with other ritual uses of mandalas, the deity evoked in the course of the ritual is located at the mandala’s center, and in this case identified with the fire itself. As a tantric ritual, the practitioner is also ritually identified with both the deity and the fire, and the offerings made into the fire are the spiritual obstacles that impede the practitioner from full awakening. Tantric homas are generally categorized according to different functions or goals, such as protection, subduing adversaries, and so on. As a form of individual practice conducive to awakening, the practitioner’s own inherent wisdom is identified with the fire, and just as the offerings are transformed and purified, the practitioner’s own spiritual obstacles are as well. Ritualized activities of maintaining and making fire are some of the most ancient forms of social coordination, which is essential to the development of the human species. Such ritualization would seem to be the basis for fire cults, forms of which are known throughout the world’s religions. In the scope of Indo-European religions, similarities of practice and symbolism provide a shared background to the homa per se. More directly, there appear to be both Vedic and Indo-Iranian traditions of ritual praxis that converge in the tantric homa. The homa is found in all of the Indic tantric traditions: Buddhist, Śaiva, and Jain. Once established as part of tantric practice, the homa was spread throughout Central, East, and Southeast Asia, particularly in its Buddhist form. This transmission of ritual practice engaged local traditions wherever it spread. Tibetan tantric traditions developed an extensive literature of homa rituals, and from there the practice also influenced Mongolian fire rituals as well. In China, interaction between tantric Buddhism and Daoism led to the creation of a homa devoted to the Northern Dipper, a figure unknown in Indian sources of Buddhist tantra. Two similar examples are found in Japan. The Shintō traditions of Yuiitsu (or Yoshida) and Miwa modified the tantric Buddhist form for the worship of a selection of Shintō deities. Similarly, the tradition of mountain asceticism, Shugendō, also adopted the homa and adapted it to its purposes. As a result of the repression of Buddhism in the third quarter of the nineteenth century, the Shintō forms are no longer extant, though in the present many Shintō shrines perform rituals of various kinds in which fire plays an important role. In contrast, the Shugendō homa, sometimes as a prelude to fire-walking, remains an active part of Japanese religion into the present day. The tantric homa has been interpreted in a variety of ways, reflecting the multifaceted character of fire itself. There are two important strains of interpretation. One is the yogic interiorization of ritual found in post-Vedic Indian religion, more as a form of esoteric physiology than as a psychologized understanding of visualization. While closely related to yogic interiorization of ritual, the sexual symbolisms that are attached to all aspects of the fire rituals constitute a second strain of interpretation. These symbolic associations are important for their role in understanding tantric notions of ritual efficacy, which require greater nuance of understanding than can be attained by simply categorizing such practices as magic.

The term tantra and the tantric traditions of Hinduism and Buddhism have been subjected to a great deal of misunderstanding in both India and the West. There is a diverse range of attitudes toward the tantric traditions, ranging from their emic understandings as paths to liberation to the relatively widespread associations of the tantric traditions with sorcery and libertine sexuality. Likewise, tantric traditions are also extremely diverse, which has made it difficult to develop a definition broad enough to cover the various tantric traditions without being overly broad. There have also been many attempts to discern the origins of the tantric traditions. While there is very little evidence supporting the hypothesis that any of the tantric traditions existed before the 5th century ce, there have been attempts to trace back these traditions much earlier, to the time of the Buddha or the ancient Hindu sages, or even back to the Indus Valley civilization. In overviewing various attempts to date these traditions, it appears that the first tantric traditions to emerge in a distinct form almost certainly first emerged in a Hindu context around the mid-first millennium ce. An overview of the history of tantric traditions, then, should begin with a survey the development of the Hindu tantric traditions, from the mid-first millennium ce up to the colonial period, when tantric traditions in South Asia generally entered a period of decline, followed by a renaissance in the 20th century. The historical appearance of Buddhist tantric traditions occurs a few centuries later, during the 7th century. Buddhist tantric traditions were strongly influenced at their inception by preexisting Śaiva Hindu traditions, but they also drew on a growing body of ritual and magical practices that had been developing for several centuries, since at least the 5th century ce, in Mahāyāna Buddhist circles. The spread of tantric traditions quickly followed their development in India. They were disseminated to Nepal; Central, East, and Southeast Asia; and also, much later, to the West. Tantric Hindu and Buddhist traditions were also a significant influence on a number of other religious traditions, including Jainism, Sikhism, the Bön tradition of Tibet, Daoism, and the Shintō tradition of Japan.
Broadly, visualization stands for a specific mode of imagination in which certain objects or concepts are “viewed as” or “viewed in light of” something else. In the religious context, something is “discovered” as the sacred in the process of visualization. In essence, what constitutes an object or image as sacred is the way this entity is encountered through visualization: it is this act that provides a surplus of value to the entity. When we visualize something, we activate multiple cognitive mechanisms and the added meaning is gained through metonymic and metaphoric structures. The new value of an entity or the discovery of new meaning is often a consequence of the blend of the existing inputs. Historically, ritualized visualization evolved in the Hindu context alongside the Vedic rituals and later became a central feature of everyday Hinduism. Tantric traditions in particular utilize visualization to gain greater access to the mechanism of the mind. Studying visualization thus not only reveals how an imaginative life meshes with reality in constituting the sacred, but it also demonstrates the power of imagination in transforming everyday reality.
