Shapeshifting Siddhis in the Chakrasamvara Tantra and Related Traditions

mim

Among the stranger subjects in tantric literature, shapeshifting remains one of the least discussed in modern Buddhist writing. Contemporary presentations of Vajrayana often reduce siddhis (magical powers) to metaphors but the older tantric sources speak in a very different voice. They describe special abilities gained through ritual practice, sexual yoga, cremation-ground rites, mantra recitation, visionary contact with yoginis and dakinis, and mastery over subtle forces in the body. One of those powers was transformation into animals and birds, especially predatory birds associated with flight, hunting, and the crossing of worlds.

The Chakrasamvara Tantra belongs to the Yogini Tantras, a class of Buddhist tantras that emerged in medieval India between the eighth and twelfth centuries. These texts were tied to charnel-ground cults, wandering siddhas, and yogini circles that existed at the edge of settled religious life. David B. Gray notes that the Chakrasamvara system was deeply connected with yogini cults and with rites considered transgressive even within Indian Buddhism.[1] The tantric world described in these texts was not symbolic in the modern literary sense. Spirits, dakinis, flesh-offerings, flight, possession, and bodily transformation were treated as concrete possibilities.

The language surrounding yoginis and dakinis is especially important because these beings were repeatedly linked to shape-changing and aerial movement. Traditional tantric vocabulary uses terms such as khecari, meaning “sky-goer” or “sky-traveler.” The yogini was understood as a being capable of moving between human and nonhuman forms, crossing physical and subtle worlds. Medieval Shaiva and Buddhist tantras describe yoginis with animal heads, bird forms, or hybrid bodies. The scholar Shaman Hatley writes that yoginis were associated with “actual shapeshifting” and with the power of flight.[2] The same literature links them to cremation grounds, nocturnal rites, and transmission of forbidden knowledge.

These themes appear in Buddhist tantric systems connected to Chakrasamvara. The dakini was not simply a poetic figure. In Tibetan commentarial traditions, dakinis could appear as women, animals, spirits, or wrathful beings encountered during ritual practice and visionary states. Judith Simmer-Brown notes that advanced tantric systems described an “outer” dakini attained through completion-stage practices involving the subtle body and its energetic transformations.[3] For advanced siddhas (tantric masters), visionary identification with animal or deity forms could culminate in actual transformation.

The Chakrasamvara cycle itself preserves traces of older tribal and shamanic material absorbed into Buddhist tantra. (For reference see my previous article titled Tantra’s Hidden Origins: Magicians, Sorcerers, and the Non-Literate World of Ancient India). The central deity Heruka stands amid cremation grounds, wearing bone ornaments and trampling Hindu deities beneath his feet. The mandala contains circles of dakinis and yoginis who embody wild and dangerous forces. Several female tantric figures connected to the tradition take animal forms. Vajravarahi herself appears with the head of a sow projecting from her temple. Animal-headed yoginis appear throughout related tantric iconography, especially in the yogini cults that influenced the Yogini Tantras.[4]

What matters here is that medieval tantric practitioners understood bodily identity as fluid. Ritual identification with a deity was already considered a real alteration of consciousness and subtle embodiment. Certain siddhis pushed this much further. Tantric manuals across both Buddhist and Shaiva traditions contain rites for invisibility, flight, entering another body, controlling spirits, and assuming alternate forms. The line between spirit possession and shapeshifting was often thin.

The predatory bird carries special weight in this material. Birds of prey appear in tantric symbolism as beings that move between earth and sky, life and death. Dakinis themselves were frequently linked with vultures, hawks, crows, owls, and carrion birds associated with cremation grounds. Tibetan art and ritual literature preserve many examples of wrathful female spirits with wings, claws, and avian features. The Tibetan term for dakini, khandroma, literally means “sky-goer.” This idea of aerial movement was not seen as fantasy. The ability to leave the body, travel through the sky, or assume bird form were skills that belonged to the siddhas’ reperatoires across India and Tibet.

Accounts surrounding the eighty-four mahasiddhas strengthen this point. These wandering tantric adepts were credited with powers that included levitation, bodily transformation, magical travel, and command over animals. Hagiographies describe siddhas appearing in unexpected forms or vanishing from ordinary sight. Luipa, one of the central figures in the Chakrasamvara transmission lineage, practiced in charnel grounds and was linked with yogini initiations involving antinomian rites.[5] These stories were preserved by tantric communities as records of attainment rather than allegories.

Parallels with Indigenous traditions elsewhere are difficult to ignore. Among several Native American nations, especially in the Plains and Subarctic regions, ritual specialists described experiences of animal transformation tied to spirit travel, hunting magic, warfare, and visionary initiation. Eagle and hawk transformations carried particular importance because birds of prey were regarded as mediators between human beings and the upper worlds. Some ceremonial societies taught that a practitioner could spiritually become the animal whose power had entered him. Similar beliefs existed among Siberian shamans, Mongolian spirit-mediums, and Central Asian ecstatic traditions.

There are important differences between these cultures, and they should not be collapsed into a single universal system. Buddhist tantra emerged within the religious environment of India, drawing from Shaiva, tribal, yogic, and cremation-ground traditions. Native American ceremonial systems developed independently within their own spiritual landscapes. Yet the recurrence of animal transformation, flight, spirit embodiment, and predatory bird symbolism across cultures suggests that these experiences belong to a wider stratum of ritual consciousness.

Modern scholars usually interpret shapeshifting language symbolically because the academic world has little room for the supernatural claims made in tantric texts. Yet even cautious historians admit that medieval tantric practitioners themselves believed siddhis were real attainments. The Chakrasamvara Tantra emerged within circles that accepted spirit contact, magical rites, visionary encounters, and bodily transformation as part of advanced practice.[6]

Reports of shapeshifting and animal embodiment did not disappear with the medieval world. In Himalayan regions, parts of Nepal, India, Mongolia, and Tibet, stories about yogis taking animal form still circulate among practitioners and villagers. Similar accounts continue among Indigenous ceremonial traditions in the Americas. Outsiders may dismiss such claims as folklore, hallucination, or symbolic storytelling, but the communities preserving them rarely make such distinctions. For them, the spirit world remains actively dangerous, and immediate.

The modern tendency to sanitize tantra has hidden much of this material. Popular books often frame Vajrayana as a system of abstract psychology wrapped in exotic symbolism. The older texts present something more unsettling. The siddha was expected to cross thresholds ordinary society feared. Cremation grounds, possession states, sexual rites, communion with dakinis and demons, and shape-changing powers formed part of the same ritual landscape. The Chakrasamvara Tantra did not emerge from a polite monastery culture detached from magic. It emerged from circles that believed reality itself could be bent through disciplined contact with forces most people feared and avoided.

Tantra’s Hidden Origins: Magicians, Sorcerers, and the Non-Literate World of Ancient India

mim

Modern scholarship on tantra has often treated it as a sophisticated religious system rooted in elite textual traditions and later integrated into high philosophical frameworks. In Buddhist contexts, especially in Tibetan scholastic traditions, tantric practice is frequently interpreted through the lens of Madhyamaka philosophy and incorporated into systematic doctrinal models. In these settings, tantra is positioned as the highest and most effective form of religious practice, supported and rationalized by philosophical analysis. There is truth in this account, but it reflects a later stage of development, the priorities of literate traditions that preserved texts, not necessarily the conditions under which tantra first emerged.

A growing number of scholars have challenged this retrospective model. Ronald M. Davidson’s study, Magicians, Sorcerers and Witches: Considering Pretantric, Non-sectarian Sources of Tantric Practices, offers a particularly forceful corrective: tantra cannot be adequately explained as the product of elite intellectual systems alone, nor as a simple inversion of orthodox traditions such as the Vedic corpus or the dharmasūtras.¹

Instead, Davidson argues that tantra must be understood within a much broader social and ritual field, one that includes non-literate practitioners whose activities long predate the emergence of tantric traditions as such. These figures, magicians, sorcerers, witches, and seers, were not marginal anomalies. They formed a durable and widespread presence in Indian religious life, operating across ancient, medieval, and even modern periods.² Their repertoire included healing, cursing, divination, spirit invocation, and various forms of ritual manipulation. These were not abstract techniques but effective practices. Some were performed in cremation grounds, involving work with corpses or restless or malevolent spirits: textual sources describe specialists who could animate a corpse or compel it to speak, a practice later associated with so-called vetāla rites. Others performed rituals to harm enemies, cure illness, or divine hidden information by invoking local deities or spirit beings. Such practices circulated widely and were recognized across Buddhist, Jain, and Brahmanical sources, even when criticized or prohibited. Many of these practices including corpse animation, harmful spells, and spirit work, would today be grouped under what is often called ‘witchcraft,’ though they were not understood as a single category in their original context.

Crucially, these practitioners were not “tantric.” They did not articulate soteriological goals of liberation, nor did they belong to the sectarian, lineage-based systems that later came to define tantric traditions.³ Their work was primarily practical rather than philosophically systematized, oriented toward immediate results rather than metaphysical coherence. Yet it is precisely this domain of practice–pragmatic, adaptive, and often non-literate–that Davidson identifies as a significant source for the later development of tantra.

This argument challenges a longstanding assumption in the study of Indian religions that authoritative origins must be found in texts. Much of the scholarship on tantra has privileged literate, intellectual traditions, in part because these are the sources that survive. But this creates a methodological distortion. If literacy rates in premodern India were extremely low, as Davidson notes, perhaps in the range of five percent, then any account of religious development that focuses exclusively on textual production necessarily excludes the overwhelming majority of practitioners.⁴ Tantra, emerging in such a context, cannot be reduced to what its later textualizers said about it.

The alternative Davidson proposes is not a single counter-origin, but a different model altogether. Rather than tracing tantra to one source, whether Vedic, Buddhist, or Śaiva, he describes a “multi-nodal” formation, meaning a network of multiple, overlapping sources in which diverse practices and traditions contribute to its development over time.⁵ Among these, the ritual activities of non-sectarian specialists play a crucial role. These practitioners developed techniques, terminologies, and ritual logics that were later appropriated by tantric communities. The process was neither systematic nor uniform. It was selective and intermittent, shaped by local needs and conditions.

In this light, tantra appears less as a coherent invention and more as a process of accumulation. Davidson characterizes this process in terms of bricolage: the assembling of new systems from pre-existing materials.⁶ Tantric traditions did not create their ritual repertoire out of nothing. They drew upon an already existing pool of practices—many of them associated with figures who operated outside the boundaries of orthodox religion—and recontextualized them within new ideological frameworks.

This perspective also clarifies why attempts to define tantra in purely oppositional terms have limited explanatory power. Some scholars have suggested that tantra emerges as a deliberate inversion of orthodox norms, particularly those codified in the dharmasūtras. Yet Davidson points out that such a model fails to account for the diversity of tantric practices. If inversion were the governing principle, one would expect a consistent pattern of reversal. Instead, the evidence reveals a heterogeneous collection of rituals, many of which do not correspond neatly to any orthodox counterpart.⁷

What this suggests is that tantra is not primarily a reaction against orthodoxy, but a reconfiguration of practices that existed alongside it. This is an important distinction. The categories of “orthodox” and “heterodox” begin to lose their explanatory clarity when we consider the extent to which ritual knowledge circulated outside formal institutions. The activities of magicians, sorcerers, and similar figures were not simply deviations from a normative system; they constituted an alternative domain of religious practice with its own internal logic.

The implications of this shift are quite significant. If tantra is, at least in part, a product of such practices, then its later intellectualization represents a secondary development. The philosophical frameworks that now define tantric traditions, whether in Buddhist or Hindu contexts, may be understood as attempts to systematize and legitimize practices that originated elsewhere.

It also complicates modern efforts to present tantra as a purely elevated or refined system. The desire to align tantra with high philosophy, particularly in contemporary interpretations, risks obscuring the conditions of its formation. Davidson’s analysis suggests that tantra’s roots lie not only in monasteries and scholastic debates, but in cremation grounds, village rituals, and the magical practices of specialists who worked with forces that formal religion often sought to regulate or marginalize.

To acknowledge this is not to reduce tantra to merely “magic,” nor to deny its later philosophical sophistication. It is to recognize that its development cannot be understood without taking seriously the contributions of those who operated outside the textual and institutional frameworks that scholars have traditionally privileged. Tantra, in this view, is not the product of a single tradition or a moment of divine revelation as is often taught. It is the outcome of a long process of interaction, appropriation, and reinterpretation across multiple domains of religious life, many of them outside the philosophical and textual traditions that later claimed to define it. In other words, tantra begins exactly where most scholars have not been looking—in the diverse and often non-literate ritual practices of magicians, sorcerers, and other specialists in ancient India.
