वर्तमानेऽपि देहेऽस्मिंश्छायावदनुवर्तिनि ।अहन्ताममताभावो जीवन्मुक्तस्य लक्षणम् ॥ ४३२ ॥
In plain words
Even though this body keeps going, tagging along after him the way a shadow does, no sense of 'I am this' or 'this belongs to me' ever touches it. That absence is the mark of the one free while still alive.
Close to the Sanskrit
Even while this body continues, following [him] like a shadow, the absence of the notions 'I' and 'mine' [regarding it] is the mark of the one liberated-while-living.
