The phrase "Mahabharata 18 Parvagala Mahakatha" (ಮಹಾಭಾರತ ೧೮ ಪರ್ವಗಳನ್ನೊಳಗೊಂಡ ಮಹಾಕಥೆ) directly translates from Kannada to:
"The Great Story of the Mahabharata, Comprising 18 Sections (Parvas)."
It refers to a complete, summarized, or simplified retelling of the entire epic Mahabharata in the Kannada language, structured according to the traditional 18 books or Parvas (sections) of the original Sanskrit text.
It is a comprehensive volume intended to give the Kannada reader the full story of the epic.
Would you like me to look up the names of all the 18 Parvas of the Mahabharata?
