Lord Chaitanya used to dance before the Rath-cart. And there is a connection between Rama-lila, Krishna-lila and Lord Chaitanya’s Lila. That’s why Lord Chaitanya has His six armed from, two arms of Lord Rama, two arms of Lord Krishna, two arms of Lord Caitanya.
Sita devi was kept with the devas, in charge of fire. Vedavati, chaya-sita took of punishment of Lord Rama. And Lord Chaitanya, He came and married Lakshmi Priya first, who was Vedavati. And she passed away, then He married Vishnu-priya, who was real Sita devi.
And Lord Krishna went from Dwaraka and met Jambavan and he realized He was Lord Rama-chandra. And he gave his daughter Jambavati in marriage to Lord Krishna. So, these three lilas are connected.HH Jayapataka Swami Speech – Ratha Yatra Festival
