Blended reading (Sanskrit + English inline)
uddaṇḍa nṛtya prabhu kariyā huṅkāra cakra-bhrami bhrame yaiche alāta-ākāra
When Śrī Caitanya Mahāprabhu danced and jumped high, roaring like thunder and moving in a circle like a wheel, He appeared like a circling firebrand.
Purport
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.
— A.C. Bhaktivedanta Swami Prabhupāda
