Indian classical dance, or Shastriya Nritya, is an umbrella term for various performance arts rooted in religious Hindu musical theatre styles, whose theory and practice can be traced to the Sanskrit text "Natya Shastra".
Karnabharam or "The Anguish of Karna" (literally: "The Burden of Karna") is a Sanskrit one-act play written by the Indian dramatist Bhasa, an Indian playwright complimented even by the famous Kalidasa in the beginning of his play Malavikagnimitram .
 The play describes the mental pain of Karna on the previous day of the Kurukshetra War.
 Karnabharam is essentially the retelling of an episode of the Indian epic Mahabharata but the story is presented in a different perspective in the play.
 It is perhaps the only potential tragedy in the classic Sanskrit literature, presented in a form that comes closest to the "Vyayoga" (Sanskrit: व्यायोग) form of one-act play.
 That is so perhaps because the Natya Shastra ordains the playwrights to create plays for recreation, and essentially create happy endings .
 In Karnabharam, the tragedy does not occur on-stage (Unlike Urubhanga, a tragedy that shows Duryodhana dying - again, written by Bhasa).
 Karnabharam shows the valiant, generous, righteous Karna riding out towards the battle-ground, where his death under heart-wrenching circumstances is certain.
 The basic plot of this play is inspired by Mahabharata.
Abhinaya (Sanskrit "abhi-" 'towards' + "nii-" 'leading/guide') is the art of expression in Indian aesthetics.

Manifestations of Shiva is a 1980 documentary film (90-minute) about the Hindu god Shiva's worship.

Indian classical dance is an umbrella term for various codified art forms rooted in Natya, the sacred Hindu musical theatre styles, whose theory can be traced back to the Natya Shastra of Bharata Muni (400 BC).
 Various classical dance events are held annually across India in various cities.
Bharata Muni was an ancient Indian theatrologist and musicologist who wrote the Natya Shastra, a theoretical treatise on ancient Indian dramaturgy and histrionics, especially Sanskrit theatre.
 Bharata is considered the father of Indian theatrical art forms.
 The "Nattiyam" comprises 36 chapters and is possibly the creation of more than one scholar.
 It dates from between the 3rd century BCE and the 1st-century CE.
Shilparatna is a classical text on traditional South Indian representational-performing arts.
 It is particularly influential in painting and theatrical performance.
 It was authored by Srikumara in 16th century AD.
 In this the word "Shilpa" (sculptural) "Ratna" (Gems) is used as a broad term embodying artistic forms that either uses the body as a medium of expression (like Dance, Drama or Dance-Drama) or that which represents the body as an expression (like Sculptures and mural arts).
 It ranks only after the Natya Shastra and the Abhinaya Darpana as a text of fundamentals on the performing arts.
A bansuri is a side blown flute found in many parts of India and Nepal, and a musical instrument that is common in the North Indian or Hindustani classical music.

 The "bansuri" flute is an ancient musical instrument of the Indian subcontinent.
 It is called "nadi" and "tunava" in the "Rigveda" and other Vedic texts of Hinduism.
 Its importance and operation is discussed in the Sanskrit text "Natya Shastra".
Brihaddeshi is a Classical Sanskrit (dated ca. 6th to 8th century) text on Indian classical music, attributed to Matanga Muni.
 It is the first text that speaks directly of the raga and distinguishes the classical ("marga") and the folk ("desi").
 It also introduced sargam notation.
 In Matanga's discussion of musical scales and micro-tonal intervals he clarifies Bharata Muni's Natya Shastra on which the author based his work.
 It clarifies many issues related to shruti that were presented tersely by Bharata.
