देहोऽयमन्नभवनोऽन्नमयस्तु कोशोह्यन्नेन जीवति विनश्यति तद्विहीनः ।त्वक्चर्ममांसरुधिरास्थिपुरीषराशि -र्नायं स्वयं भवितुमर्हति नित्यशुद्धः ॥ १५६ ॥
In plain words
This body, which comes into being from food, is exactly what we call the food-sheath: it lives on food, and it perishes when deprived of food. It is nothing but a heap of layers of skin, flesh, blood, bone, and waste. Something like that simply cannot be the eternally pure Self.
Close to the Sanskrit
This body, born of food, is indeed the food-sheath; for it lives on food, and perishes when deprived of it. A heap of skin, hide, flesh, blood, bone, and excrement -- this cannot itself be the eternally pure Self.
