What is painful for saintly persons who strictly adhere to the truth? How could there not be independence for pure devotees who know the Supreme Lord as the substance? What deeds are forbidden for persons of the lowest character? And what cannot be given up for the sake of Lord Kṛṣṇa by those who have fully surrendered at His lotus feet?
Srimad Bhagavata Purana
श्रीमद्भागवतमहापुराणम्
मूल श्लोकः
किं दुःसहं नु साधूनां विदुषां किमपेक्षितम् । किमकार्यं कदर्याणां दुस्त्यजं किं धृतात्मनाम्
kiṃ duḥsahaṃ nu sādhūnāṃ viduṣāṃ kimapekṣitam | kimakāryaṃ kadaryāṇāṃ dustyajaṃ kiṃ dhṛtātmanām
