In this material world, to say this is good and this is bad has no value. To us, everything material is bad as it is lacking Krsna Consciousness. Just like wet stool and dry stool. Stool is stool, but somebody is saying that wet stool is better than dry stool. What is this good and bad? The top side of some stool is dry and the bottom side is wet, but anyway that you take it, the material world is stool, and it must be given up. Therefore, we are trying to get out of the material world and go back to Home, Back to Godhead.
But, of course, everyone has got some sentiment. If you want that my sentiment be decried, what is the wrong if I say that your sentiment should be decried. In this world of duality, this is good and this is bad has no meaning, it is called manodharma, mental concoction. However, the real truth is that Krsna says that: duhkhalayam asasvatam (BG 8.15), the world is a place of misery wherein repeated birth and death take place. Now this is good misery or bad misery? Misery is misery; and you have to die, good die or bad die? So to us everything material, without connection to Krsna, is to be rejected as stool, otherwise we will waste valuable time needed to solve the real problems of life, namely, birth, death, disease, and old-age.
