Like Bhaṭṭa Nāyaka and Mahima Bhaṭṭa, Mukula Bhaṭṭa agrees with Ānandavardhana that there are poetic phenomena that require explanation. He argues that these meanings arise from the existing category of secondary meaning, indication (lakṣaṇā), rather than the third linguistic capacity of suggested meaning. His Fundamentals of the Communicative Function, through analysis of many of the stock examples of suggestion in the Light on Suggestion, identifies the necessary features which trigger indication: an obstacle in the primary meaning, a relationship between the primary and indicated meaning, and a motive or conventional basis for the indicated meaning. Mukula argues that it is possible to have cases of indicated meaning which do not completely replace the primary meaning. Mukula’s work comes to be widely influential through its incorporation into the Illumination of Poetry (Kāvyaprakāśa) written by later philosopher of aesthetics Mammaṭa, who excerpts parts of it verbatim (McCrea 2008).
