Śaṅkarācārya's commentary

The Self has no beginning, no cause. That which has a cause perishes by itself, whereas This (Self) does not perish, because, as having no cause, He is without parts. Further, He does not perish because He is without qualities; for that which has qualities perishes by loss of qualities; whereas the Self does not perish, because He is devoid of qualities. Thus the Supreme Self is imperishable. He suffers no destruction. Therefore, though dwelling in the body — the Self is said to dwell in the body because the Self is manifested in the body — yet He does not act. Because He does not act, He is not affected by the results of acts.
