Śrī Caitanya Caritamrta · Text Madhya 22.145
জ্ঞান-বৈরাগ্যাদি — ভক্তির কভু নহে ‘অঙ্গ’ ।
অহিংসাযম-নিয়মাদি বুলে কৃষ্ণভক্ত-সঙ্গ ॥ ১৪৫ ॥
jñāna-vairāgyādi — bhaktira kabhu nahe ‘aṅga’
ahiṁsā-yama-niyamādi bule kṛṣṇa-bhakta-saṅga
“The path of speculative knowledge and renunciation is not essential for devotional service. Indeed, good qualities such as nonviolence and control of the mind and senses automatically accompany a devotee of Lord Kṛṣṇa.
