CC Madhya 18.111
jīvādhame ‘kṛṣṇa’-jñāna kabhu nā karibā!
Śrī Caitanya Mahāprabhu immediately exclaimed, “Viṣṇu! Viṣṇu! Do not call Me the Supreme Personality of Godhead. A jīva cannot become Kṛṣṇa at any time. Do not even say such a thing!
Śrī Caitanya Mahāprabhu immediately stated that a living being, however exalted he may be, should never be compared to the Supreme Personality of Godhead. All of Śrī Caitanya Mahāprabhu’s preaching protests the monistic philosophy of the Māyāvāda school. The central point of Kṛṣṇa consciousness is that the jīva, the living entity, can never be accepted as Kṛṣṇa or Viṣṇu. This viewpoint is elaborated in the following verses.
