The Natya Shastra, attributed to the sage Bharata Muni, is an ancient Sanskrit text that deals with the theory of dramaturgy and performance. It is considered the foundational work on Indian literary aesthetics and provides insights into the concepts of rasa, dhvani, and alamkara.

Rasa is the central concept in Indian literary aesthetics. It refers to the emotional experience or aesthetic enjoyment that a literary work evokes in the reader or audience. Rasa is often translated as 'aesthetic flavor' or 'sentiment'.

Bhakti is a devotional sentiment that is not traditionally included among the nine rasas in Indian aesthetics. The nine traditional rasas are Shringara (love), Hasya (laughter), Karuna (pathos), Raudra (anger), Vira (heroism), Bhayanaka (terror), Bibhatsa (disgust), Adbhuta (wonder), and Shanta (peace).

Dhvani refers to the suggestion or implication of meaning in a literary work. It is considered an important aspect of Indian literary aesthetics as it allows for multiple interpretations and layers of meaning within a text.

Alamkaras are poetic devices used to enhance the beauty and expressiveness of language in Indian literature. Simile, metaphor, personification, and alliteration are all examples of alamkaras.

Riti refers to the use of specific poetic conventions, such as meter, rhyme, and language, in Indian literature. It is often associated with particular schools or movements of poetry.

Abhinavagupta, Anandavardhana, Mammata, and Jagannatha are all prominent literary critics in the history of Indian aesthetics. They have made significant contributions to the development of theories and concepts related to rasa, dhvani, alamkara, and other aspects of Indian literary criticism.

Vakrokti refers to the use of indirect or oblique expression in Indian literary aesthetics. It involves saying something in a roundabout or suggestive way, rather than directly stating it.

Irony is an example of a gunibhuta vyangya in Indian aesthetics. It involves saying something that is the opposite of what is meant, or using words in a way that suggests a different meaning than the literal one.

Rasa-dhvani refers to the suggestion of rasa through dhvani in Indian literary aesthetics. It involves using dhvani to imply or suggest a particular rasa in the reader or audience.

Cliché, tautology, and mixed metaphor are all examples of doshas (faults) in Indian literary aesthetics. They are considered to be flaws in writing that can detract from the overall quality of a literary work.

Anuprasa refers to the use of alliteration in Indian literary aesthetics. It involves the repetition of the same consonant sound at the beginning of successive words or syllables.

Simile, metaphor, and personification are all examples of gunibhuta alamkaras in Indian aesthetics. They are considered to be poetic devices that can enhance the beauty and expressiveness of language in a literary work.
