O Brahmana, they are not opposed to one another; they exist in proper combination. When this universe is thrown into a state of chaos then every corporeal being in proper time assumes another body. It perishes also in due order.
अन्योन्यं नातिवर्तन्ते सम्यक् च भवति द्विजा यदा तु विषमं भावमाचरन्ति चराचराः॥ तदा देही देहमन्यं व्यतिरोहति कालतः। आनुपूर्व्या विनश्यन्ति जायन्ते चानुपूर्वशः॥
