आहार निद्रा भय मैथुनश्च ,सामान्यमेतत पशुभिर्नराणाम ।
धर्मोतेषांअधिको विशेषः, धर्मेण हीनः पशुभिस्समानः ॥


Hunger, sleep, fear, and physical pleasures are common to both animals and human beings. It is the adherence to Dharma that distinguishes human beings from animals.
Without Dharma, human beings and animals are the same.
