prema-āveśe - in ecstatic love; puṣpa-udyāne - into the garden at Guṇḍicā where the Lord stays; karibena praveśa - will enter; sei-kāle - at that time; ekale - alone; tumi - you; chāḍi' - giving up; rāja-veśa - the royal dress.

“On that Ratha-yātrā festival day, after dancing before the Lord, Śrī Caitanya Mahāprabhu will enter the Guṇḍicā garden. At that time you should go there alone, without your royal dress.
