‘bhaṭṭācārya’ tumi iṅhāra nā jāna mahimā
bhagavattā-lakṣaṇera iṅhātei sīmā
bhaṭṭācārya — my dear Bhaṭṭācārya; tumi — you; iṅhāra — of Lord Caitanya Mahāprabhu; nā — not; jāna — know; mahimā — the greatness; bhagavattā — of being the Supreme Personality of Godhead; lakṣaṇera — of symptoms; iṅhātei — in Him; sīmā — the highest degree.
“My dear Bhaṭṭācārya, you do not know the greatness of Lord Caitanya Mahāprabhu. All the symptoms of the Supreme Personality of Godhead are found in Him to the highest degree.”
Since the Bhaṭṭācārya was an impersonalist, he had no idea of the Absolute Truth beyond the impersonal effulgence. However, Gopīnātha Ācārya informed him that Caitanya Mahāprabhu was the Supreme Personality of Godhead. Those who know the Absolute Truth know it in three phases, as explained in Śrīmad-Bhāgavatam (1.2.11):
vadanti tat tattva-vidas tattvaṁ yaj jñānam advayam
brahmeti paramātmeti bhagavān iti śabdyate
“Those who are in knowledge of the nondual Absolute Truth know very clearly what is Brahman, what is Paramātmā, and what is the Supreme Personality of Godhead.” The Supreme Personality of Godhead is ṣaḍ-aiśvarya-pūrṇa, complete with six opulences. Gopīnātha Ācārya emphasized that all those six opulences were completely existing in Śrī Caitanya Mahāprabhu.
