Bhagavad Gita 3.9

3.9 The world is bound by actions other than those performed for the sake of sacrifice; do thou, therefore, O son of Kunti (Arjuna), perform action for that sake (for sacrifice alone), free from attachment.

Work done as a sacrifice for Viṣṇu has to be performed; otherwise work causes bondage in this material world. Therefore, O son of Kuntī, perform your prescribed duties for His satisfaction, and in that way you will always remain free from bondage.
