Understanding Tantra: Origins, Authority, and Reputation — Rajarshi Nandy

The author traces the word to the root 'tan', meaning to stretch, weave, make, or form systems via principles and teachings — evoking the image of weaving many threads into one fabric leading toward spiritual fulfillment. In general use, the term has come to mean systematic knowledge governing devata upasana and its allied applications. He notes this isn't a late invention: tantric allusions appear as far back as the ancient Atharvaveda and in some Vedic Brahmana literature.

To support tantra's authority, Nandy quotes Kulluka Bhatta — the well-known commentator on the Manusmriti — who wrote "vaidiki tantriki caiva dvividha sruti kirtita," which the author reads as placing the tantras at the level of shruti, the core Vedic texts considered the ultimate spiritual authority in Hindu literature.

The author walks through the four ages (chaturyugas): in Krita/Satya Yuga, humanity followed Vedic ritual directly; as capacity declined through Treta Yuga, the smritis (law codes, epics) became the guide; by Dwapara Yuga even those became too burdensome, so the Puranas were given; finally, in Kali Yuga, humans are said to lose most of their capacity to draw in prana except through solid food, and Mahadeva is said to have revealed the tantras as the path suited to this diminished, "corrupted" age — capable of bestowing both bhoga (worldly enjoyment) and moksha (liberation).

The author describes the AgamaA body of Tantric scriptural injunction (such as Shivagama) specifying rules for worship, including where and how sacrifice is sanctioned — violating its rules for mere taste or sensory enjoyment forfeits any higher spiritual attainment.s as texts conveying ritual knowledge for deity worship and temple ritual, generally classified by their main deity (Saiva, Shakta, Vaishnava). In 4th–5th century Kashmir specifically, the classification ran Saiva, Rudra, and Bhairava — with Saiva Agamas dualistic in cosmology (a division between soul, isvara, and world), Rudra mixing dualistic and non-dualistic views, and Bhairava Agamas staunchly non-dualistic, proclaiming the unity of existence. It was largely from these Bhairava Agamas, he says, that Shakta Tantra — centered on the Divine Feminine, Shakti — developed and gave structure to much of contemporary tantric upasana.

The author names a specific line of masters as central to Kashmir Shaiva Tantra's development between the 7th and 12th centuries: Vasugupta, credited with receiving the Shiva Sutras; then Somananda and Utpaladeva; culminating in Abhinavagupta, described as the polymath who systematized the entire philosophical and practical framework of Kashmiri Shaiva Tantra.

The author gives one generic classification scheme for tantras based on adherence to accepted Vedic (Vaidika) social and ritual norms: Siddhantika Tantras conform to those codes, while non-Siddhantika Tantras take a more heterodox approach. He notes that what is popularly known today as "tantra" — involving the heterodox pancha makara — falls entirely under the non-Siddhantika category, i.e. it is not representative of tantra as a whole.

Beyond Kashmir's foundational contributions, the author describes tantra as having shaped Bengal (Gauda) and South India distinctly. Kashmir's Saiva Tantras, especially before the region's historical disruption, emphasized intricate philosophical inquiry. The Kalikula system, prominent in Bengal and centered on the fierce Goddess Kali, tends toward practical ritual application instead. The Srividya tradition, refined and influential in South India (though practised elsewhere too), maintains what he calls a sophisticated balance between sadhana and philosophy.

Nandy describes a two-pronged colonial-era attack on tantra's reputation. Christian missionaries, seeking to discourage Hindus from their ancestral dharma and encourage conversion, systematically spread false information portraying Hindu deities and tantra as primitive, superstitious, and immoral. Separately — and, he suggests, partly in reaction to that same Western pressure — some Hindu leaders and reformers began emphasizing the aspects of Hinduism (non-duality, an impersonal Brahman) that resonated with Western sensibilities, while downplaying or suppressing deity worship, leaving tantra doubly disparaged as "primitive superstition."

Beyond external misrepresentation, the author names an internal cause: seekers without strong ethical and spiritual guidance entering the tantric field lured by the prospect of siddhis (supernatural powers) — a term he says is itself widely misunderstood as mere magic — and applying tantric methods for selfish reasons. This, he argues, inevitably led to their own downfall while doing lasting damage to the reputation of the tantra shastras, perpetuating the false idea that tantra is a form of inferior occultism, black magic, or jadu tona.

The author holds up Sir John Woodroffe as one of the earliest and most outspoken colonial-era defenders of the tantra shastras. Woodroffe rose through the British Indian judiciary to become Chief Justice of the Calcutta High Court. He was drawn to tantra after a case where his mind repeatedly and mysteriously "fogged up" — his clerk theorized a hired tantric practitioner had been engaged by one of the parties to chant mantras influencing the judge, and Woodroffe's clarity reportedly returned once the man was removed from the court. This incident led him to study Sanskrit and eventually be initiated into tantra sadhana, reportedly reaching a high-order initiation called Purnabhisheka. Writing under the pseudonym Arthur Avalon, he translated rare tantric manuscripts and wrote pioneering books — including Principles of Tantra and The Serpent Power — establishing a philosophical basis for tantric practice against missionary and reformist criticism.

The author distinguishes tantra from paths oriented solely toward liberation: in tantric philosophy, the world is the direct manifestation of Shiva's shakti, engaging in lila (divine play), so there is no fundamental split between transcendent divinity and worldly life. He sees this reflected in how most stotras and stutis end by invoking the chaturvarga phala — dharma, artha, kama, and moksha together — and notes that two of tantra's primary deities, Kameshwari and Kameshwara, are themselves considered the source of all desire in the universe. Exclusive pursuit of moksha alone, he argues, is properly reserved for sanyasis who have formally renounced the world — not the standard expectation for the rest of practitioners.

In the course of recounting his own early sadhana, the author explains the concept of parivara devatas — attendant deities that exist in the retinue of every major deity in the Hindu pantheon, each with distinct functions and powers, and who must also be propitiated during the upasana of the primary deity. He states that when a sadhaka generates sufficient spiritual power through dedicated practice, these attendant deities may first visit or test the practitioner before the main deity decides to manifest, directly or indirectly — and that any strict timeline for this is impossible to fix, since it depends on each individual's own karmic burden (samskaras) from past lives.
