The imperishable Supreme Self, being beginningless and without gunas, neither acts nor is tainted though dwelling in the body. Shankara explains that Brahman is beyond all modification and therefore untouched by the body's activities. Ramanuja teaches that God dwells in the body as the inner controller without being affected by the body's karma. The Bhakti tradition marvels at the Lord's purity even while intimately present in every embodied being. Madhva explains that the Supreme Self is not contaminated by the body, just as the soul shares this quality through its spiritual nature under God's protection. Abhinavagupta teaches that the imperishable Self neither acts nor is tainted because it is pure self-luminous awareness — the body's activities occur within consciousness without affecting its essence. Vallabha explains that God's pure nature cannot be diminished by contact with matter — even while sustaining the body, the Lord remains in fullness. Tilak encourages action without fear of contamination: if the Supreme Self acts without taint, the karma yogi can engage in duties without spiritual harm. Vivekananda teaches that your essential nature cannot be corrupted — this is the basis for rebuilding any life.
