You can't judge a book by its cover means that when you have only seen the surface of something, you cannot know what is on the inside. "Don't go falling in love with that girl so fast. Wait until you get to know her better.

I opine that what I have in me I superimpose on others and claim they are either good or bad! I also feel there is no need to be judgmental- who am to judge the other?- if I go about judging an individual, I am certain-I will have no time to love him! Again coming back to what I have in me only -I can find in others! Examples are: Keep pelting a full bloom mango tree with stones, what in turn it gives you- Mango only. Is it not- it has no stones to give ! Also eyes can see only, cannot hear, smell. taste or touch. Why, because it is its character- similarly apply the theory on us, what I have with me only, I can understand! If I don't have that with me, how can I understand! So let us be good, we can make the world good. Why go about judging, because Niccolo said! Sorry Ananthu, I bored you early in the morning!
