I couldn't find a specific poem titled "Maninagar Kavithai," but if you're looking for Tamil poetry, there are many wonderful collections available online. You might enjoy exploring [this collection]( https://www.tamildigitallibrary.in/kalaignar/01.literature/kavithaigal.html ) or [this one]( https://www.valaitamil.com/literature_poem ) for a variety of Tamil poems. If you have a particular theme or poet in mind, I’d be happy to help you find something more specific! 😊
