Āveśa (Sanskrit) refers to a state of spiritual possession or divine inhabitation in which a deity or sacred power “enters” and dwells within a person. The word literally means “an entering” or “fusion,” describing the incorporation of divine power into the human body. Such forms of sacred possession have long been central to Indian Tantric practice, invoked for both worldly benefits (bhoga) and spiritual liberation (mokṣa). This is often contrasted with demonic possession in Christian theology, typically characterized as an involuntary affliction by an evil spirit.
Cross-cultural studies note that spirit possession can be either voluntary or involuntary, and it is interpreted differently depending on the tradition. Western occult traditions, such as Luciferianism, may view possession by a demon as desirable, even leading to a so-called “perfect possession.” In Christianity, however, even voluntary possession by a demonic force is considered evil. The question then arises: who or what possesses the practitioner in Eastern contexts?
Towards the end of my 35 years in Tantric Buddhism, I came to believe that the force presenting itself as a deity was, in fact, demonic. In what follows, I will examine the phenomenon of āveśa in two major esoteric traditions, Hindu Tantra (especially Shaiva lineages such as Kashmir Shaivism), and Tibetan Vajrayāna Buddhism. I will contrast these forms of divinely sanctioned possession with demonic possession in Christian and occult frameworks, drawing from historical sources, academic analysis, and personal experience.
Āveśa in Hindu Tantric Traditions
Scriptural Origins and Tantric Development
The Sanskrit root ā-viś (to enter) appears in early Indian texts, foreshadowing the later Tantric elaboration of āveśa.1 From the 5th to 11th centuries, Tantric scriptures across Śāiva, Śākta, and Buddhist milieus incorporated āveśa into ritual practice. Scholar Vikas Malhotra describes āveśa as the “entrance or fusion of oneself with the deity,” central to both magical and liberatory goals.2
These practices utilized mantras, mudrās, and nyāsa (installing mantras on the body) to induce the deity’s presence. Often this process was linked to śaktipāta, or the descent of divine energy. Over time, āveśa came to refer not just to deity possession, but a range of spiritual states culminating in union with Śiva.3 In contrast to exorcism (removing evil spirits), this adorcistic form of possession aimed to invite a divine presence.
Kashmir Shaivism and Samāveśa
In the Trika system of Kashmir Shaivism, the term samāveśa refers to full ontological immersion in Śiva-consciousness. Abhinavagupta, a 10th-century Hindu philosopher and Tantric adept, defined it as a merger of individual and divine being, sometimes accompanied by shaking, trance, or devotional ecstasy.4 Rituals such as nyāsa or advanced mudrā usage were seen as ways to divinize the body. Kṣemarāja, a key Trika commentator, emphasized that the body itself becomes a vessel for cosmic forces, eroding the sense of ego.5
This idea extended to daily ritual. The practitioner installs divine presences into various body parts—e.g., “May Brahmā be in my genitals, ViṣŇu in my feet, Śiva in my heart”—until the self is transformed.6 Āveśa was also connected to śaktipāta dīkṣā (initiation by grace), which Abhinavagupta saw as the guru’s transmission of divine force into the student.
Historical sources and hagiographies portray this not as pathology but sacred awakening. In the Bhakti tradition, saints like Caitanya and Rāmakṛṣṇa exhibited signs interpreted as divine possession, a loss of ordinary consciousness during worship or dancing in states of trance. In goddess worship, the ecstatic state of bhāva can evolve into full possession by a fierce Devī or goddess.
Induced Trance in Ritual Practice
Possession is not accidental; it is often deliberately induced. Contemporary folk-Tantric rites like Theyyam in Kerala reenact this vividly. The performer undergoes intense ritual preparation, dons a sacred headdress, and becomes a vessel for the deity. His demeanor, voice, and movements change dramatically, and devotees approach him as a god.7 These techniques including fasting, music, sacred garb, and mantra, parallel ancient Tantric rituals meant to induce āveśa.
Importantly, this experience is consensual. A priest may invite a deity for oracular guidance or blessing. The Tantric yogi similarly invites identification with Śiva. As Frederick Smith notes, such possession is the most valued spiritual experience in many Indian settings.8 Advanced yogis even practiced para-kāya praveśa, the entry of one’s consciousness into another’s body, a form of high-level āveśa.9
Āveśa (Possession) in Tibetan Vajrayāna Buddhism
Deity Yoga and Guru Inhabitation
Though the term “possession” is less used, Vajrayāna emphasizes divine inhabitation. In Deity Yoga, one visualizes oneself as a yidam (meditational deity) and invites the deity’s wisdom aspect (jñānasattva) to merge with the visualization (samayasattva). Through mantra and meditation, the practitioner dissolves ego and identifies as the deity.
While framed as an enlightened act, in practice there is no safeguard against malevolent forces. Many Tibetan rituals derive from the Yoginītantras, esoteric texts filled with wrathful, dangerous dākinīs. These entities are unpredictable and must be carefully propitiated. Practitioners hope to merge with them for wisdom and power, but failure often results in spiritual collapse or madness. One either becomes “enlightened” or is destroyed.
My personal experience, including participating in two three-year retreats, led me to conclude these deities are not divine but demonic. After prolonged practice, I experienced terrifying possession states, torturous sensations, and an uncontrollable kundalini awakening. While there were moments of bliss and magical phenomena, the final result was spiritual devastation.
Guru Yoga and Transmission
Guru Yoga, especially in the Nyingma and Kagyu lineages, mirrors āveśa. The practitioner visualizes the guru dissolving into them, merging body, speech, and mind. This is intended to produce an inseparable union. Some historical accounts even describe instant enlightenment via physical gestures or verbal commands from a master, a form of mind-to-mind transmission akin to possession.
Some Vajrayāna practices involve obvious demon possession. The Nechung Oracle, for example, enters trance during elaborate rituals, allowing the deity Pehar to possess his body. Frightening physical changes, voice alteration, and strength are observed. The practice is structured around phowa, a method of ejecting consciousness to allow divine entry.10
Possession as Initiation and Transformation
Both traditions treat āveśa as transformative. In Hindu Tantra, samāveśa may mark initiation or realization. In Vajrayāna, empowerment rituals symbolically install the lineage mindstream into the disciple. When successful, the practitioner believes they have merged with divine consciousness.
The experiences are often euphoric and expansive. Yet, as I learned, they can also become nightmarish. The forces one invokes may not be what they seem. While traditions insist the entities are enlightened or benevolent, there is no proof. Many undergo trauma, dissociation, and spiritual breakdown.
Christian Views of Possession: A Stark Contrast
In Christian theology, possession is demonic by nature. The demon enters uninvited or through occult involvement, and exorcism is the remedy. Symptoms include revulsion to the sacred, altered voices, and loss of control. Unlike tantric āveśa, the demon is not a divine aspect but an evil other. (I should note that the kundalini energy always felt “other” to me, but I was encouraged to see it as a positive experience.)
Catholic doctrine states that even voluntary occult involvement is condemned, seen as opening a door to bondage; the soul remains untouched, but the body and mind may be dominated. Consent may be partial or misguided, but once entered, the demon seeks destruction.
Only the Holy Spirit is seen as a positive presence, and even then, Christian traditions speak of inspiration rather than possession. Some Pentecostal expressions resemble Eastern possession states, but many Christians believe these, too, are counterfeit Holy Spirit experiences linked to kundalini phenomena.
Scripture offers stern warnings:
All the gods of the nations are demons.” — Psalm 96:5 (Septuagint) “They sacrificed to demons, not to God.” — Deuteronomy 32:17
In conclusion: āveśa is framed as a sacred merging in Tantra, but my experience revealed it as demonic deception. Beneath the ritual beauty lies spiritual subjugation. As an exorcist once warned me: Be careful who or what you invite to abide within.
