CC 2.19.167: “ ‘When first-class devotional service develops, one must be devoid of all material desires, knowledge obtained by monistic philosophy, and fruitive action. The devotee must constantly serve Kṛṣṇa favorably, as Kṛṣṇa desires.’

Text â„–
Renunciation also means being exclusively dedicated to the Lord and indifferent to what stands in the way of His service.
