In English
Seventh: Whatever books you read or whatever you write should be pure. This is the relating to study - . If you read or write that which is not pure, it warps your mind. A good book makes for a good mind. Any book you may study about Physics or Chemistry or other subjects, does not affect your character. But books which are literary, are not always good literature. If improper books are prescribed for study, treat them as mere text-books and do not attach any high value to them as guides for life.
