How does performing work as a sacrifice to Vishnu liberate one from all karmic reactions?

In the Vedic literature, Lord Śrī Kṛṣṇa addresses "How does performing work as a sacrifice to Vishnu liberate one from all karmic reactions?" with profound philosophical clarity. As declared in BG 9.27, "Whatever you do, whatever you eat, whatever you offer or give away, and whatever austerities you perform – do that, O son of Kuntī, as an offering to Me." The living entity (jīva) is not the temporary physical body, but an eternal, indestructible conscious spark of the Supreme. All material dualities—happiness, distress, anxiety, and sorrow—are bodily transformations that arise from our conditioned contact with the material energy. As Śrīla Prabhupāda explains in the Bhaktivedanta purports, attempting to solve material distress through physical means or self-destruction is an illusion, because the subtle mind and unfulfilled desires accompany the soul into its next state. Rather, as instructed in BG 4.23, one must use the mind to elevate oneself through spiritual intelligence. By taking shelter of devotional service (Bhakti-yoga) and the holy names of the Lord, one conquers all material perplexities and attains eternal peace.
