But you're not "loaning" it to your mother; you're creating another copy of the book and GIVING that copy to your mother. Two people have a copy of the book where only one had it before. That's the fundamental difference between an eBook and a paper book, and that's why it's piracy.
There's nothing wrong with lending your mother your reading device with the book on it - that way, only one person has the eBook, and there's no piracy.
