Here’s a glimpse of the holy bathing ceremony of the Panca Tattva last Gaur Purnima at Sri Radhe Kunj in Vrindavan. We are singing the Gaur purnima kirtan (by Srila Krishna Das Kaviraj Goswami in Sri Chaitanya-charitamrita, Adi-lila, ). Turn on subtitles to sing along with the kirtan. English translation here
nadīyā-udayagiri, pūrṇacandra gaurahari,
kṛpā kari’ ha-ila udaya
pāpa-tamaḥ haila nāśa, tri-jagatera ullāsa,
jagabhari’ hari-dhvani haya (98)
Thus by His causeless mercy the full moon, Gaurahari, rose in the district of Nadia, which is compared to Udayagiri, where the sun first becomes visible. His rising in the sky dissipated the darkness of sinful life, and thus the three worlds became joyful and chanted the holy name of the Lord.
