Sometimes the devotees have a false conception, to think, “If I am surrendered to Kṛṣṇa, that means I shouldn’t have to suffer.”And then they become doubtful, “I surrendered so much to Kṛṣṇa – why should I have to suffer?” But the Lord minimizes the suffering. And minimization of the suffering means that we deserve a lot more than what we got. But minimization also means that whatever suffering the devotee has to experience now, presently, is actually burning up his previous reactions to sinful life, so that his future is bright – and in that way also Kṛṣṇa is minimizing the suffering of a devotee. That’s why Kṛṣṇa says mā śucaḥ... “Don’t fear! Your future is bright! Why are you fearful?”
