NS VI.68-72 names bhayānaka — the Terrible Sentiment — with the Dominant State of fear (bhaya) at its base.1 What makes Bharata's treatment specific is the three-fold structure of the rasa's Determinants. Fear arises from three distinct source-categories:
Environmental triggers: hideous noise, sight of ghosts, panic about jackals and owls (untimely cries), staying in an empty house or forest.
Supernatural triggers: sight of death or captivity, encounters with otherworldly beings, the body's response to the uncanny.
Interpersonal triggers: news of captivity or death of dear ones, discussion of such events, offending one's superiors or the king.
The framework treats these as substantively different even though they produce the same dominant state. The fear of the empty forest is not the fear of the angry king; the fear of the ghost is not the fear of news-of-death. Modern adaptation often collapses these into "fear" generically; the three-fold structure recovers the discrimination.
NS VI.68 lists the Determinants compactly: "hideous noise, sight of ghosts, panic and anxiety due to untimely cry of jackals and owls, staying in an empty house or forest, sight of death or captivity of dear ones, or news of it, or discussion about it."2
Consequents (VI.68-70): trembling of the hands and feet, horripilation, change of colour, loss of voice, "looseness of the limbs, the mouth and the eyes, paralysis of the thighs, looking around with uneasiness, dryness of the drooping mouth, palpitation of the heart."3 The body's signature is seizure — the limbs lose coordination, the mouth dries, the eyes scan defensively, the body's normal motor-control fails.
Transitories: paralysis, perspiration, choking voice, horripilation, trembling, loss of voice, change of colour, fear, stupefaction, dejection, agitation, restlessness, inactivity, epilepsy, death.4 The transitory list is one of the longer ones in the rasa system — bhayānaka draws on many of the body's involuntary-system responses, because fear specifically engages the involuntary system.
NS VI.71 makes a craft-distinction: "This is the character of natural fear; the artificially shown fear also should be represented by these conditions. But in case of the feigned fear all efforts for its representation should be milder."5
The distinction matters. A character who is genuinely afraid (the protagonist in danger) and a character who is feigning fear (the deceiver pretending threat) require different performance intensities. Bharata names this 1700 years before the modern subtext-and-performance literature works out the same insight. The framework supports both real and feigned fear as legitimate dramatic outputs — but requires the performer to know which is being delivered and modulate the somatic signature accordingly.
NS VI.80 names the Terrible's three sub-kinds: feigned fear, fear from wrong action, fear from apprehension of danger.6
These do not align directly with the three Determinant-categories (environmental/supernatural/interpersonal). They are a different axis: feigned (performed-without-truth), reactive-to-wrong (the guilty character's fear), anticipatory (the threat-not-yet-arrived fear). The dual three-fold structure (three sources × three modes) gives the rasa nine combinatorial variants, though the framework does not develop the full grid.
The Terrible rasa is the engine of horror, suspense, thriller, and tragic-anticipation content. Bharata's framework gives modern adapters tools they often lack:
As trigger-discrimination diagnostic. Most horror content operates in only one or two of the three Determinant-source categories (usually supernatural and environmental). The third (interpersonal-fear-of-the-powerful, news-of-loss, fear-of-the-king) is underused in contemporary horror but is foundational to political-thriller and tragic-anticipation work.
As body-signature precision. Modern fear-acting often produces generic fear — "scared" performances that fail to specify the Bharata-named somatic signature (paralysis of thighs, dryness of mouth, looking-around-with-uneasiness, palpitation). Naming the signature beats produces more readable fear on screen.
As feigned-vs-natural distinction. Scenes where a character is pretending to be afraid (to deceive, to manipulate, to perform vulnerability) require different acting than scenes of real fear. NS gives the craft-rule: milder somatic signature for feigned fear. Modern screen-acting often does not articulate this distinction, producing feigned-fear that reads as the same intensity as natural fear and consequently as performed.
Three Determinant-sources vs three sub-kinds: NS provides two orthogonal three-fold structures (source-categories at VI.68; sub-kinds at VI.80) but does not develop their interaction. Whether each source-category can produce each sub-kind, or whether specific combinations are reserved, is unclear.
Natural-feigned distinction at body-signature level: the rule that feigned fear should be milder is operationally precise but psychologically counter-intuitive. Real fear is often more constrained than performed fear (the truly terrified person freezes; the actor playing terror often over-emotes). Whether Bharata's rule reflects the empirical reality or a stylized convention is open.
Terrible vs Pathetic vs Vipralambha: all three can carry the loss-of-loved-ones determinant. Bharata distinguishes them by which inner state dominates — fear (Terrible), grief (Pathetic), separation-with-optimism (Erotic-in-Separation). Modern scripts often slide between these without marking the transition; the framework's rasa-purity discipline would catch the slippage.
Bharata is the single primary source. The productive tension is between his natural-rule treatment (real fear has these somatic signatures) and his feigned-rule treatment (performed fear should be milder). Both are in VI.71 within two sentences.
This is the actor's craft-distinction. The real-fear body and the performed-fear body are different bodies. Modern Method-Acting tradition sometimes collapses them — the actor's job is to be afraid, with the implication that the body will automatically produce the right signature. Bharata's framework refuses this: even genuine inner-fear must be performed at appropriate intensity for the dramatic context, and feigned-fear-by-the-character must read as feigned to the audience. The craft is in the gradation, not just in the summoning.
The Terrible rasa is an eastern-spirituality page, but the underlying claim — that fear is a tri-source somatic state with specific body-signature — runs into adjacent vault domains.
psychology: Somatic Trauma Theory — modern somatic-trauma-theory describes fear-states with body-signatures that closely match Bharata's: paralysis (the "freeze" response), trembling, voice-loss, dryness-of-mouth, palpitation, hypervigilance ("looking around with uneasiness"). The structural identity is exact at the body-signature level. What differs: trauma-theory describes these as involuntary responses to threat; Bharata's framework treats them as both involuntary (in genuine fear) and summoned (in skilled fear-acting). Combined, the two frameworks describe the same nervous-system response from different operational angles — clinical (what the body does under threat) and dramatic (how to render the body's threat-response on stage). The insight: trauma's somatic signature and skilled fear-acting's somatic signature are the same signature, produced by different generative routes. Modern trauma-informed acting could draw on this — and modern screen-acting that needs to render trauma accurately could use the trauma-theory literature to refine the somatic signature.
behavioral-mechanics: Walter's Five Preconditions for Terror — the behavioral-mechanics framework on terror-induction names the structural conditions under which fear-states can be deliberately produced in target populations. The structural parallel to bhayānaka is operational — Walter's framework specifies what produces terror in a population; Bharata's specifies what terror looks like once produced. Combined: the terror-induction architecture (Walter) + the terror-rasa display (Bharata) describe the full operation from cause to observable response. The insight: dramatic rendering of terror and operational induction of terror in target populations are not separate phenomena — they share the same somatic substrate, and both rely on similar Determinants (interpersonal threats from the powerful, environmental uncertainty, news-of-violation). This is uncomfortable territory but theoretically important: skilled terror-content in entertainment and operational terror-induction in influence work draw on the same nervous-system mechanism.
The Sharpest Implication
If you take Bharata's three Determinant-categories seriously, modern horror genre is operating with about two-thirds of the available fear-vocabulary. Environmental horror (the empty house, the strange sound) and supernatural horror (the ghost, the inexplicable) are well-developed; interpersonal-political horror (the fear of the powerful, the news-of-the-loss, the offending of authority) is mostly the territory of literary fiction and political thriller rather than the horror genre itself. The framework names this gap as structural: NS treats the three sources as equally legitimate, and the contemporary horror tradition has narrowed to two-thirds. Recovery would expand horror substantially — raudra often runs alongside bhayānaka in interpersonal-political content, and the genre's renewal may depend on developing the third Determinant-category as fully as the other two.
