कर्मणां च विवेकार्थं धर्माधर्मौ व्यवेचयत् । द्वन्द्वैरयोजयच्चैमाः सुखदुःखादिभिः प्रजाः ॥ २६ ॥
Moreover, in order to distinguish actions, he separated merit from demerit, and he caused the creatures to be affected by the pairs (of opposites), such as pain and pleasure.
यं तु कर्मणि यस्मिन् स न्ययुङ्क्त प्रथमं प्रभुः । स तदेव स्वयं भेजे सृज्यमानः पुनः पुनः ॥ २८ ॥
But to whatever course of action the Lord at first appointed each (kind of beings), that alone it has spontaneously adopted in each succeeding creation.
यथर्तुलिङ्गान्यर्तवः स्वयमेवर्तुपर्यये । स्वानि स्वान्यभिपद्यन्ते तथा कर्माणि देहिनः ॥ ३० ॥
Whatever he assigned to each at the (first) creation, noxiousness or harmlessness, gentleness or ferocity, virtue or sin, truth or falsehood, that clung (afterwards) spontaneously to it.
यथर्तुलिङ्गान्यर्तवः स्वयमेवर्तुपर्यये । स्वानि स्वान्यभिपद्यन्ते तथा कर्माणि देहिनः ॥ ३० ॥
As at the change of the seasons each season of its own accord assumes its distinctive marks, even so corporeal beings (resume in new births) their (appointed) course of action.
