The dog is running on legs, and they are running on cars. So, (laughs) actually what is the difference? This is advancement of civilization, that the dog is running for nothing, here and there on legs, and human being is running on nice car. Does it mean there is advance in civilization? If we keep the human being like cats and dogs, without any advancement of knowledge, the cats and dogs, they cannot accept any advanced knowledge. That is not possible. Similarly, if human society is kept in darkness without any advanced knowledge, without any knowledge of the aim of life and without any knowledge what is the meaning of human life, they’ll remain as cats and dogs. So as cats and dogs, if they are practiced to run here and there, either on legs or on cars, is that advancement of civilization?
