O Nagarâja! The Holy (Dol) festival in the month of Chait on tha third day of the white fortnight is very pleasing to Me and should be observed by all. My devotees perform the S'ayanotsava in the Paurnâmâsî in the month of Âsâdha; the Jâgaranotsava in the Paurnamâsî in the month of Kârtik, the Ratha Jâtrâ in the 3rd of the white fortnight in Âsâdha; the Damanotsava in Chaitra. And my dear festivals in the month of S'râvana and various other festivals.
