CC Ādi 7.60
মহাতেজোময় বপু কোটিসূর্যাভাস ॥ ৬০ ॥
mahātejomaya vapu koṭi-sūryābhāsa
After sitting on the ground, Caitanya Mahāprabhu exhibited His mystic power by manifesting an effulgence as brilliant as the illumination of millions of suns.
Śrī Caitanya Mahāprabhu, as the Supreme Personality of Godhead Kṛṣṇa, is full of all potencies. Therefore it is not remarkable for Him to manifest the illumination of millions of suns. Lord Śrī Kṛṣṇa is known as Yogeśvara, the master of all mystic powers. Śrī Kṛṣṇa Caitanya Mahāprabhu is Lord Kṛṣṇa Himself; therefore He can exhibit any mystic power.
