Guru Maharaj: Karma may cause you to suffer and enjoy in the material world. That cannot interfere with your devotional service unless you let it. So, if you become very enamored by the happiness of the material life or become very depressed by the suffering of material life, then it can affect you. If you are committed to serving Kṛṣṇa in spite of whatever happiness or distress happens, then nothing can stop.
