CC Madhya 18.100
“mūrkhera vākye ‘mūrkha’ hailā paṇḍita hañā
Māyā is so strong that even a person like Balabhadra Bhaṭṭācārya, who was constantly staying with Śrī Caitanya Mahāprabhu, was influenced by the words of fools. He wanted to see Kṛṣṇa directly by going to Kālīya-daha, but Śrī Caitanya Mahāprabhu, being the original spiritual master, would not allow His servant to fall into such foolishness. He therefore chastised him, slapping him just to bring him to a real sense of Kṛṣṇa consciousness.
