The Sanskrit love poem Kokila Sandeśa was modeled upon the Meghadūta of Kālidāsa, which was in turn primarily based on what type of Indian writings?
Kokila Sandeśa The Kokila Sandeśa (Sanskrit: कोकिलसन्देश) or "The Message of The Koel" is a Sanskrit love poem written by Uddanda Śāstrī in the 15th century AD. A short lyric poem of 162 verses, it describes how a nameless hero, abducated from his wife’s side by mysterious women, sends a message to her via a koel. The poem belongs to the sandeśa kāvya, (‘messenger poem’) genre and is modelled upon the Meghadūtaof Kālidāsa. It is one of the most famous of the many sandeśa kāvya poems from Kerala.
Hamsa Upanishad The Hamsa Upanishad (Sanskrit: हंसोपनिषद् ) is a Sanskrit text and a minor Upanishad of Hinduism. It is classified as one of the twenty Yoga Upanishads, and attached to the "Shukla Yajurveda". The text or parts of the text is a relatively late origin, probably from the 2nd-millennium of the common era, but written before early 17th-century, because Dara Shikoh included it in the Persian translation of the Upanishads as "Oupanekhat", spelling it as "Hensnad" (Hamsa-nada).
