Śrī Caitanya Caritamrta · Text Madhya 22.82
মহৎসেবাং দ্বারমাহুর্বিমুক্তে-
স্তমোদ্বারং যোষিতাং সঙ্গিসঙ্গম্ ।
মহান্তস্তে সমচিত্তাঃ প্রশান্তা
বিমন্যবঃ সুহৃদঃ সাধবো যে ॥ ৮২ ॥
mahat-sevāṁ dvāram āhur vimuktes
tamo-dvāraṁ yoṣitāṁ saṅgi-saṅgam
mahāntas te sama-cittāḥ praśāntā
vimanyavaḥ suhṛdaḥ sādhavo ye
“ ‘It is the verdict of all śāstras and great personalities that service to a pure devotee is the path of liberation. By contrast, association with materialistic people who are attached to material enjoyment and women is the path of darkness. Those who are actually devotees are broadminded, equal to everyone and very peaceful. They never become angry, and they are friendly to all living entities.’
