The devotees, who are always engaged in the service of the toes of the lotus feet of the Lord, can very easily overcome hard-knotted desires for fruitive activities. Because this is very difficult, the nondevotees — the jñānīs and yogīs — although trying to stop the waves of sense gratification, cannot do so. Therefore you are advised to engage in the devotional service of Kṛṣṇa, the son of Vasudeva.
