Consequently, they cannot be part and parcel of devotional service; rather, they have no intrinsic value in the discharge of devotional service. When one is freed from bondage to the results of knowledge and fruitive activities, he can attain to devotional service. Since a devotee of Lord Kṛṣṇa is by nature nonviolent, and since his mind and senses are controlled, he does not have to make a special effort to acquire the good qualities which result from cultivating knowledge and performing fruitive activities.
When Uddhava was asking Kṛṣṇa about rules and regulations according to Vedic injunctions, he asked, "Why is it that the Vedic hymns encourage one in material enjoyment, while at the same time the Vedic instructions also free one from all illusion and encourage one toward liberation?" The Vedic rules are supposed to be ordained by the Supreme Personality of Godhead, but apparently there are contradictions, and Uddhava was anxious to know how one could be freed from these contradictions. In reply, Lord Kṛṣṇa informed him of the superexcellence of devotional service.
