Is that true??

Hey You, Tell me who has come & Pleaded you not to sell your Books ? Just go ahead & sell them ! & Understand one thing clearly,

People who dont sell their Books are more of those who have Respect towards their Books & Studies & People like you making this type of Questions & thoughts are People who dont have the Respect for Books & Studies. 

Have a Glass of Cold water & Give a Thought to what I said & you will get the answer to your Question
