I have written a book called 'In the Wonderland of Numbers. ' It's about a young girl, Neha, who is very poor in mathematics, but in a series of illusory experiences, she becomes a great mathematician.
The longer men sin, the more easily they can; for every act of transgression weakens conscience, stupefies intellect, hardens hearts, adds force to bad habits, and takes force from good example. And, surely, there is nothing in such associations; as wicked affinities will insure to the sinner in the future state, to incline him to repentance.
