Śrī Caitanya Caritamrta · Text Madhya 24.104
সাধুসঙ্গ, কৃষ্ণকৃপা, ভক্তির স্বভাব ।
এ তিনে সব ছাড়ায়, করে কৃষ্ণে ‘ভাব’ ॥ ১০৪ ॥
sādhu-saṅga, kṛṣṇa-kṛpā, bhaktira svabhāva
e tine saba chāḍāya, kare kṛṣṇe ‘bhāva’
“Association with a devotee, the mercy of Kṛṣṇa, and the nature of devotional service help one to give up all undesirable association and gradually attain elevation to the platform of love of Godhead.
