For [one] free from attachment, liberated, thinking fixed in knowledge,
Actions undertaken for sacrifice entirely melt away.

Source: Milind S. Pandit

Those who are devoid of attachment, whose mind is fixed in knowledge, who does work as a Seva to the Lord, all Karma of such liberated persons dissolves away.

Source: The Bhagavad-Gita: The Sacred Song

The work of a man who is unattached to the modes of material nature and who is fully situated in transcendental knowledge merges entirely into transcendence.
