uddaṇḍa - jumping; nṛtya - dancing; prabhu - Śrī Caitanya Mahāprabhu; kariyā - making; huṅkāra - loud vibration; cakra-bhrami - making a circular movement like a wheel; bhrame - moves; yaiche - as if; alāta-ākāra - circle of fire.
If a burning cinder of a firebrand is whirled about very swiftly, it gives the appearance of a circle of fire. This is called alāta-ākāra or alāta-cakra, a firebrand circle. This whole circle is not actually made of fire but is a single fire in motion. Similarly, Lord Śrī Caitanya Mahāprabhu is a single personality, but when He danced and jumped high in a circle, He appeared like the alāta-cakra.
