Radhastami is the celebration day of Srimati Radharani's appearance. Radharani is the consort of Krishna. She appeared to Vrishabhanu Maharaj (her father) in the village of Rawal a fortnight after Krishna’s appearance.
Radharani's special qualification is that She is the best devotee of Krishna. Krishna therefore loves Her the most. On Her festival day, devotees seeking Krishna's grace will especially ask Her to grant them devotion to Her beloved Lord, knowing that if they can attain Her favor, they can attain His as a natural consequence.
On Radhastami, Sri Sri Radha Krishna deities are traditionally dressed entirely in flowers. Sri Sri Radha Rasabihari are offered a new outfit in the morning and adorn a flower outfit in the evening.
The festivities on Radhastami includes darshan of Sri Sri Radha Rasabihari in new outfits, spiritual discourses, kirtans and bhajans, maha-abhishek, maha-arati and offering of hundreds of bhoga foodstuffs to Their Lordships. The special highlight of the day is a magnificent boat festival where the Utsav-murti of Sri Sri Radha Rasabihari are taken on a flower bedecked silver boat in the temple courtyard.
