Śrī Caitanya Caritamrta · Text Ādi 5.148
আচার্য–গোসাঞির তত্ত্ব না যায় কথন ।
কৃষ্ণ অবতারি যেঁহো তারিল ভুবন ॥ ১৪৮ ॥
ācārya-gosāñira tattva nā yāya kathana
kṛṣṇa avatāri yeṅho tārila bhuvana
I cannot describe the truth of Advaita Ācārya. He has delivered the entire world by making Lord Kṛṣṇa descend.
