So the situation of the world, due to ignorance of the soul they are creating so many sinful activities and becoming entangled. But they have no knowledge how they are becoming entangled. This is maya's, praksepatmika-sakti, avaranatmika. Although he is being entangled, but he's thinking that he's advancing, advancing in scientific knowledge. This is their knowledge. The gentleman was talking that he's a mining engineer. So mining engineer, his business is to make the atmosphere within the mine very comfortable. Just imagine, he has gone down within the earth just like the mousehole, and he's improving that mousehole. After being educated, after getting degrees, his position is to enter into the dark, dark, I mean to say, hole of the earth, and he's trying to scientific advancement by cleansing the air within the mine. He's condemned that he has been forced to give up the outer, outer space, free air. He has been condemned to go within the earth, and he's proud of scientific advancement. This is going on. This is scientific advancement.
