A Tibetan Buddhist Dzogchen master and a Kashmiri Śaiva Tāntrika belong to different religions, different countries, different centuries, different scriptural canons. Yet when Wallis lays their core teachings side by side, he reports something startling: "I have not yet been able to identify a significant difference between the two schools."1 Dzogchen — "the Great Perfection," the pinnacle teaching of the Nyingma Buddhists and the Bön — teaches that everything is Consciousness (rigpa), formless and absolute yet possessing definite qualities. And those qualities, when you list them, map almost exactly onto nondual Śaiva Tantra. Same View, two flags.
The convergence Wallis documents has several precise points:2
The upshot for Wallis: "Tantra was and is a spiritual phenomenon that is transreligious."7
The point isn't trivia about cross-cultural similarity. It's a claim about what Tantra fundamentally is. If a Buddhist school and a Śaiva school, with no doctrinal incentive to agree (they'd normally compete for adherents and truth-claims), independently arrive at the same description of ultimate reality and the same qualities of awareness — then the thing they're describing is plausibly not a sectarian doctrine but a recognizable feature of consciousness itself that different traditions stumbled onto and dressed in different vocabularies.
This is why Wallis can call Tantra "transreligious." The convergence functions as a kind of triangulation: two independent witnesses describing the same territory raises the odds that the territory is real and not a shared cultural artifact. And it cuts against the academic habit of treating mystical claims as wholly constructed by their traditions — because if rigpa and cit are genuinely the same recognition, the recognition isn't made by Tibetan Buddhism or by Kashmiri Śaivism; it's found by both. The shared geography (Uḍḍiyāna) hints that there may even have been historical cross-pollination, but Wallis's stronger claim doesn't need it: even if the two arose independently, they're pointing at one thing.
This convergence is the capstone of Wallis's "transreligious Tantra" thesis, extending the many-names-one-Reality logic across religions. It centers on the Krama (the Śaiva school closest to Dzogchen) and feeds directly into why Wallis recommends the Krama for modern Westerners (its Dzogchen-alignment is one of his reasons). It rests on the equation rigpa = cit/saṃvit and the shared Uḍḍiyāna origin in Tantric history.
The most concrete evidence Wallis offers is a list — the qualities Dzogchen ascribes to rigpa — and it's worth reading as the actual data behind the "no significant difference" claim. Rigpa, though formless and absolute, possesses: indestructibility, incorruptible purity, nondiscriminating openness, flawless clarity, profound simplicity, all-pervading presence, and equality within all beings — unconditioned, uncaused, and blissful.8
Run each against nondual Śaiva Tantra and the match is uncanny. Indestructibility and unconditioned/uncaused — the Śaiva Self is never created and never destroyed, the ground that all things rest in. Incorruptible purity — mala is ignorance, not a real stain; the essence-nature was never actually defiled. Nondiscriminating openness and all-pervading presence — Consciousness pervades all things equally, the "no degrees of God" teaching. Equality within all beings — every being is Śiva in relative degrees of self-concealment. Flawless clarity and blissful — prakāśa (Light) and ānanda (Bliss), two of the core divine powers. Profound simplicity — the absolute beyond all the elaborate maps. Point for point, the Dzogchen description of awareness is the Śaiva description of Consciousness, with the proper names swapped out. The case study shows the convergence isn't a vague "all paths lead to the same place" platitude — it's a specific, item-by-item correspondence between two traditions' technical accounts of the ultimate, which is a far stronger and more falsifiable claim.
For a practitioner, the convergence is a practical permission and a navigation aid. Treat the vocabularies as interchangeable, carefully. When a Dzogchen text speaks of resting in rigpa, you can read it as resting in cit/saṃvit — the same recognition pointed at, so the View you've learned in one transfers to the other. Use the better-preserved tradition to illuminate the attenuated one. Dzogchen survives as a living practice lineage with intact transmission; Śaiva Tantra is heavily attenuated. So Dzogchen's living instructions on resting in awareness can fill gaps where the Śaiva practice-transmission is broken — which is precisely why Wallis tells readers drawn to the Krama but more at home in Buddhist aesthetics to "feel very much at home with a good Dzogchen teacher."9 Don't collapse them carelessly, though. Their common ground is at the level of the View and the nature of awareness; the ritual forms, deities, and cultural framings differ, and a responsible practitioner keeps one root (one well, not a dozen holes) rather than blending two transmissions into mush.
Lazy perennialism (all-paths-are-one mush). You take the convergence as license for "it's all the same, labels don't matter" and blend traditions indiscriminately, losing the precision of both. But Wallis's claim is specific (item-by-item correspondence of the View), not a vague universalism that erases real differences in method, ritual, and lineage. The tell: a smooth "all religions teach the same thing" that can't actually name the seven qualities or distinguish the View-convergence from the method-differences.
Overstating the historical link. You treat the shared Uḍḍiyāna origin as proof that one tradition simply copied the other, turning a "probably not coincidental" geographic rhyme into a hard derivation. Wallis is careful: the stronger claim (they describe the same reality) doesn't depend on historical borrowing. The tell: confident assertions of direct transmission where the evidence supports convergence, not causation.
A comparative claim Wallis makes with explicit epistemic humility — he flags that his inability to find a difference "may be due to my relative ignorance of Dzogchen."10 That hedge is the honest crux. They agree on striking, but it's reported by one scholar-practitioner deeply formed in the Śaiva tradition, who might be pattern-matching Dzogchen onto categories he already holds. The open question is whether a Dzogchen master, equally expert, would agree that there's "no significant difference" — or would point to distinctions (the Buddhist emptiness/no-self framing vs. the Śaiva full-Self framing, for instance) that look major from the other side. The deepest unresolved issue: does the convergence prove a shared reality both traditions found, or a shared contemplative grammar that produces similar descriptions without guaranteeing an identical referent?
The most interesting tension hides inside the convergence itself: Buddhism is famously a tradition of anattā (no-self) and śūnyatā (emptiness), while nondual Śaivism is a tradition of the full Self (pūrṇa, the "I am everything" of pūrṇo'ham vimarśa). On paper these look like opposites — empty of self vs. full of Self. Yet Wallis claims Dzogchen and NŚT converge with "no significant difference." How? Dzogchen is the Buddhist school that least fits standard Buddhism — it "declares itself beyond Tantra" and holds views "not so clearly Buddhist" precisely because they're so close to Śaiva. So the convergence works partly because Dzogchen has drifted toward a positive, quality-rich description of awareness (rigpa has qualities — clarity, bliss, presence) that strains the strict emptiness framing. Pull on that and you find the real question the convergence raises: is "empty awareness" (Buddhist) and "full Consciousness" (Śaiva) a genuine disagreement, or two rhetorics for one recognition — where "empty" means empty-of-fixed-content and "full" means full-of-potential, and both are pointing at the same open, luminous, present awareness? The convergence of the one Buddhist school that broke the emptiness mold with the Śaiva fullness tradition suggests the empty/full divide may be more about emphasis and inherited vocabulary than about the awareness itself — which would be a remarkable thing for two "rival" religions to accidentally demonstrate.
The plain link: this is a case of independent traditions converging on the same description of consciousness — which speaks to the psychology of contemplative/unitive states and to the comparative study of how authority and orthodoxy keep traditions apart.
The Sharpest Implication If a Buddhist school and a Śaiva school — different religions, no incentive to agree — independently describe ultimate reality point-for-point the same, then the labels "Buddhist" and "Hindu," and maybe "religion" itself, are not tracking the deepest level of what these traditions found. The destabilizing part: the thing the contemplatives are pointing at appears to be transreligious — a feature of consciousness that different cultures discovered and renamed, not a doctrine any one of them owns. That reframes the entire landscape of spiritual sectarianism. The disagreements between traditions, fierce as they are, may live almost entirely in the delivery systems — the rituals, deities, scriptures, social identities — while the recognition at the center is one recognition. And if that's true, the seeker's loyalty question shifts: the choice between traditions stops being a choice about which is true and becomes a choice about which delivery system fits you — which is a far more practical and far less anxious question than the sectarian framing makes it.
